For online shoppers, whether you’re shopping for computer hardwares, softwares, or even domain names, you won’t forget to search and find out what are the valid coupon codes for you to enter and hence get discounts from the deals.

Coupon codes, or promo codes, you know when you want it, you want it so badly at the time when you check out that item. Frankly, I’ve seen many blogs, forums or sites that offer coupon codes in a way that the codes are either submitted by the users themselves or as a result of Web aggregation. The famous one is RetailMeNot, but there’s a new entrant to this realm; a new site called Bargn.

Bargn is a newly launched site that shows the valid coupon codes which mostly are submitted by the users. You can save money with the online coupon codes when you check out the items at some well-known vendors such as GoDaddy (domain names), HP & Dell (computer parts), 1-800-FLOWERS.COM (flowers), Adobe softwares, and many more. However, the coupon codes available on Bargn are mainly focused on online deals, and without the clear stated of expiration date. But you always can assign a “+” or “-” symbol to rate how well the coupon codes have worked for you.

ResearchGATE is essentially a professional network for scientists. Dubbed as Science 2.0, this site has a very clean look, and the contents are slit up in an easy to navigate menus. At first glance, ResearchGATE is a closed community, which only restricted scientists and researchers to interact with each other, and view each others’ profiles, although one can still sign-up to the site and connect with some of the scientists and researchers with a profile opened there.

Positioned as a social network for scientists. ResearchGATE mentioned it as a professional network, which is a different way of saying social network for professionals, as I perceived; Perhaps many of us will asked do the scientists and researchers around the world need a social site that they can interact each other with?

From a scientist and researcher’s standpoint, it is a good idea to merge the social and research aspects together around the science disciplines so that they can converse with each other based on the research areas. In particular, scientists and researchers can share work and idea with each other, they called it “discussion partners,” or collaborate in a given project on ResearchGATE. However, as a site visitor, you only can query its search engine and read the abstracts of the papers pertaining to your areas of interest, or busy yourself with the tag cloud listed on the sidebar.

To know more about ResearchGATE, it has collaborated with various international research institutions and organizations such as European Students’ Conference, IALS, REBIRTH, etc. in order to build a strong network system for the scientists and researchers.

There are tweeters around believe that mixing their tweets along with pictures is cool, and after I profiled the Plurkpix last year, many third-party Twitter app are being developed and emerged just to fulfill those need of tweeting the image for the tweeters.

The following are the few among them that offering the image interactive with Twitter.

1) TweetPhoto

For those who have a Facebook profile, by supplying your Facebook details in the TweetPhoto’s Facebook app can give you the option to publish your photo and share it with your Facebook friends.

Meanwhile, for the photo you’ve mixed with your tweet, you can retweet it with the number of characters left in your first tweet.

2) TwitPic

With the fantastic rate of over 6,000 users a day and over 1.5 million users overall, TwitPic is perceived by many as one of the best Twitter third-party app on the Web. Like the aforesaid, you also can tweet the image via their Web interface or email by using the secret PIN TwitPic given to you. For the image tweeting, you can either show the photo in a tiny URL link or hide the photo in your Twitter account.

To know how many people are using TwitPic, you can visit its front page that show the recent photos uploaded by the tweeters in a geo-tagging manner. Kudos to Noah Everett as he is creating and maintaining this app himself, at the time of my writing.

3) SnapTweet

As the site’s tagline, SnapTweet is a Twitter third-party app that connect Flickr to Twitter. It has a fairy smooth interface which makes users easy when they want to share Flickr photos on Twitter. Just enter your Twitter username, password, and Flickr URL, and it’s done.

But if you want to know the statistical view of whom has visited your picture and how many people in total have seen it, you get it.

A simple addition that makes this Pixim more useful in general is that tweeters can now post pictures to Pixim from Tweetie.

Although the world has already entering recession, there are still many people willing to go for a good vacation provided they found the cheap flights and hotel deals. To fulfill the need of this aspect, instead of searching one hotel after another across the Web, probably you’ll need to check out this TravelPost, one of the premier ways to find the hotel reviews even before you check out a particular official hotel site.

Currently, TravelPost aggregates nearly 2 million hotels around the world. The search function is simple, simply submitted either by city or hotel name and some keywords suggested by search assistant will help you personalize your search preferences based on your travel option. While most of the hotel reviews are the results of aggregation from some established sites such as Yahoo! Travel, IgoUgo, BedandBreakfast.com, epinions, PerfectEscapes and MyTravelGuide, there are still many of the best hotels out there that haven’t been reviewed by its users.

On the front page, there is also a Google Maps app rotated with some markers that show the geotagged photos of hotel reviews written by TravelPost’s users recently. In fact, TravelPost is a nicely built hotel review site. Each hotel reviewed you’ll find the basic info of the hotel such as photo, map, address, check-in, check-out time, popularity ranking as well as the most important one to the hotel deal hungry travelers, i.e. the rate calendar. Of course, you won’t forget to read the hotel reviews before you make up your mind to stay with a particular hotel.

WHERE’S COOL is a new online community for travelers, with a specific focus on travel reviews of the places that your mom probably wouldn’t find useful, as mentioned on the front page. Though it’s in Alpha stage, but users are allowed to register with the site at this moment and start the travel reviews for some cool spots such as the record shops, dive bars, hostels, live music and underground local attractions, etc.

Currently, there are several destinations from Taipei, Taiwan to Kraków, Poland have been reviewed by the users, and each review is detailed with photos, text reviews, and geo-tagging in order to provide a comprehensive travel recommendations for other users who want to plan their next vacation to the same travel destination. Of course, users can also comment and rate others’ travel experiences. Nevertheless, if you are the type of person who is the free and easy traveler and like the local adventure, you’ll find this site most useful for this purpose.

In overall, WHERE’S COOL is a site for discovering local information. For instance, when I been in Taiwan and traveled as a free and easy traveler, some photos listed there urges me to go there for a second look such as this Shilin Night Market which I missed the food so much. As the site still in Alpha, I hope this site can make to the mainstream so that people can have another place to share their travel experiences and places of interest.
