Rails Rumble: Micro-App Competition Winners Announced

In 48 hours last weekend, 237 developer teams competed and generated a total of 137 qualifying web applications, all developed with Ruby and Rails on the back end.
The 2009 Rails Rumble was, according to organizers, the strongest yet in the contest's history. (Disclosure: I was on the 'expert panel' of judges for the Rumble and got a sneak peak at a significant handful of apps.)
As microapps (as this particular brand of simple, single-function sites and widgets could be called) occupy an ever-increasing tract of Internet real estate, time-crunch events such as Startup Weekend and Rails Rumble serve as tests of skill and team-building challenges, not to mention endurance competitions as developers burn through hour after sleepless hour. Yet with each cycle, these events do produce a number of noteworthy apps that might grow into something more in the weeks and months to follow while teaching all developers valuable lessons about simplicity in interface design. Here's a quick breakdown of the eight winning Rails Rumble applications.

El segundo lugar, correspondio a un grupo de desarrolladores uruguayos de ruby, que hicieron una aplicacion para revisar codigo, que esta muy buena...

First Place: Hi.Im

Hi I'm is (yet another) service that aggregates a user's social streams to a centralized location, sort of like Retaggr, Chi.mp, and their ilk. The idea wasn't the most innovative, as many of the 80 comments on this project noted, but the user experience was as simple as following the yellow brick road. The app was developed by San Jose-based web/mobile development shop Koombea.

Second Place: How's My Code?

How's My Code is a peer review tool for developers to comment on, approve of, and flag commits. Email notifications allow users to come back to ongoing discussions. If you spend more time on GitHub than Facebook, this might be an app for you to check out.
