ROCK YOUR HACKERS is COOOOOOL !!!
We've been seeing more Ohloh widgets in the wild lately. Here's a few examples:
Rock Your Hackers Facebook App
Rock Your Hackers allows you to praise, promote, and in no uncertain terms shout for joy about your favorite free and open source software projects (FOSS) and then share your "Hack List" with your friends (and perhaps fellow hackers)! Wave the banners of your favorite FOSS projects for all your "faceworld" to see.
Drupal Plugin
This module allows users, with the right permissions, to display their Ohloh profiles in their Drupal account page. It will also facilitate any future integrations with Ohloh.
ikiwiki Shortcut
Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git. It also features a handy ohloh shortcut.
QuickSilver Websearch Plugin
If you use quicksilver on the mac, you can quickly search projects ohloh using the websearch plugin.
Got an idea for a new widget? Check out our REST API docs. It's free and easy to use. If you'd like to discuss it, come also join us on IRC - irc.freenode.net at #ohloh.
I developed a PHP client for the Ohloh API that is also included in the Chisimba framework. Not much has been done with it yet, but it has gotten some interest!
Along the same line, I've hacked a small http://userscripts.org/scripts/show/25525 to display Perl's modules' Ohloh badges on CPAN. There's more details about it at my http://use.perl.org/~Yanick/journal/36234.
