Prohmote, an event planning tool that built on top of Google App Engine, using the Python and Django Templating is a no-registration required service that allows you to plan your own event. It has a very clean and simple one-page interface, and by simply type in the details of your upcoming event, you can create the event in seconds. However, you’ll need to provide your email address during the event creating process, so that you can keep track of your event, and share it with your members, friends, and family. After you creating the event, the event profile displays the basic info of the event, and the event URL is carried with an unique URL name, comprised of number and character letter.

Prohmote also features privacy option, which allows you to determine the event you created is publicly be seen or in private invite only. Additionally, there is also a RSVP system to allow guests to confirm if they will attend or no, and a mini feed so that you can keep up with the latest update of the event.

To know more about Prohmote, it is an event planning tool that went into beta in March this year. And it seems like Prohmote planned to launch a Pro version that allow enterprises to pay for their paid accounts with Google Checkout in the near future.

Matt (aka The Mattinator) is a new Web application that let users to post to multiple Twitter accounts without having to log into each one every time. It was developed by a team of Web developers that based in the U.K. As a long-time reader of some Web design magazines printed in the U.K., my first impression on this site is that it was a Web product from the U.K., albeit that I’m having the difficulty in justify their color choices of the elements in their Web design.

Fundamentally, I didn’t see the logic for one Twitter user to open few Twitter accounts, and she desperately need to get a Web application to help her solve the multiple login problems, but the birth of this site has the positive effect on the other end. The way I look at this site, Matt was more of an experiment to see how quickly they could build an entire new site with a programming language, i.e. Python that they’re not familiar with, and a Python Web framework, i.e. Django within four days. And of course, with the Twitter API as well. This will help convince more programmers in using Web frameworks when they’re looking for fast development, and potential users can test out the product in a shorter time frame.

EveryBlock is a grant project created by a co-founder of Django namely Adrian Holovaty. It is a site that allowed users to keep track of the data on every block of Chicago, New York and San Francisco, three cities initially upon launched in January 23 this year. Now if you go to the site, more cities are covered at this moment since they’ve included Charlotte and Philadelphia (June 30, 2008), Boston, Seattle, Washington, DC (August 18) and the latest addition is Los Angeles (August 27).

EveryBlock is one of the early leaders in local news aggregation. In a motto, “A news feed for your block,” this site offers the latest news feed of what is happening in the neighborhood in the cities aforesaid. So far, EveryBlock is particularly useful when users want to know the latest photos taken, real-estate listings, geographic cataloging of local media or blogs in the cities concerned. Though all these data are pull from some third-party applications such as Flickr, Panaramio (photo), Trulia (real-estate listings), Yelp (business reviews), Craigslist (lost-and-found), media, mainly local relevant newspapers or blogs, EveryBlock seemed to offer a broader assortment of local news, with much greater functionality than those offered by the local newspapers. This make sense with the almost-instant updates of crime, fire alerts, restaurant food closures and inspections that are freely available on the site. Those data are obviously important for users who live in dense areas such as New York with lots of stuff going on in every second.

Undoubtedly, the present success of EveryBlock should be attributed by its smart partnerships with Government bodies such as New York State Liquor Authority, Chicago Tribune, the Mecklenburg County Health Department, just to name a few. With the help of these bodies, all the public records and information can be passed to the public instantly with a ZIP code search in the search bar. If you can’t think of anything to search on this EveryBlock, you can test it out by simply browse to the latest news feed by type, such as graffiti cleaned in New York, liquor licenses, and etc.

Meanwhile, EveryBlock is up against a bigger competition, in viewed of its recent move to the private transport sector by launching a EveryBlock DashApp that enable drivers to view the latest EveryBlock data in their cars.
