Tumblr has been around for more than 2 years, started its offering as an easiest blogging platform for its users has added a feature which I think most of the Internet surfers would love to use.

This new feature called Tumblupon is a new way to help Internet surfers to stumble across interesting Tumblr postings based on a user’s likes. To use this feature, it is very easy and accessible without any toolbar download. In fact, a user simply need to click the “Tumblupon Controls” that sits in the left-hand side of the top menu, and a new Tumblr blog post will be shown on the browser whenever a new click is done.

Although this feature can be found on any social browsing site, but with the size of 650,000 posts per day in August this year, and the number is growing every day, it’s good to note that this Tumblupon will allow you to read some good posts you didn’t even find on the Google search.

To share things online, there is a mini-blogging service called Posterous. It works quite similar to Tumblr, which means when you get started, you can get the option of post a note, a photo, URL link, video, MP3, or a file via email or mobile phone (U.S. only), and all of your entries will be shown in a beautiful and elegant manner.

On Posterous, each of the entries will be presented in three elements, i.e. heading, content, and comment. If you only post the photo, or video such as YouTube clip as the content of all of your entries, without any written text and heavily based on graphical use, you’ll find the consistency of your Posterous entries presented on the Web, and visitors would likely know your life-stream or your daily-life via the photo or video clip found on your Posterous. Other than the aforesaid features, all users’ Posterous will have its own customized URL, as the username you chosen will be served as the sub-domain of the customized URL on Posterous.

By exploring Posterous, there are many well written Posterous blogs and if you find one you like, you can subscribe to it by clicking the “Subscribe” link beneath the user’s Posterous. Also, if you like one of the entries, you can favorite it. However, from a commodity feature point of view, the most notable feature in Posterous probably is the post an entry by using email. After a user signing up to this Posterous, she can start to post things on her profile via email. Simply email Posterous at post@posterous.com using the email you signed up to the service and they’ll reply instantly with your new Posterous blog. I’m one of the Posterous users, and frankly, I like the prompt submission of my entry within a few seconds.

Other than that, Posterous recently also launched the “Autopost” feature. This Autopost allows you to post your entry to your Posterous, in the mean time also post it to some other platforms such as your registered Facebook, Twitter, Flickr, Tumblr, Blogger, WordPress, TypePad, Movable Type, LiveJournal and Xanga account. Not to mention they also introduced the tagging feature, a feature will become a strong welcome addition that allows your Posterous to be discovered by Google or other blog search engines through all the tags you entered. Similarly to Tumblr, you also can use your custom domain name for your Posterous. However, as a personal users, you’ll only get the storage space of 1G for your account.

Overall, though I believed that Posterous would like to be the central hub for one in posting mini-blog, and it seemed like they’re dare to try new things, it will be interesting to see if they will succeed in the crowded mini-blogging sphere in the long run.

To know more about Posterous, it is co-founded by Sachin Agarwal and Garry Tan, both are graduates of Stanford University. Posterous also a Y Combinator-funded company.
