I'm looking for an open-source tool that is used to monitor releases of new versions of open-source software and is built using a plug-in architecture (one plug-in for each app that must be monitored).
This is a generic task, at least for package maintainers, so I believe there are such tools and I won't have to write something up myself.
I've created a google account and added these tools' news feeds to Google Reader which displays RSS for me. For projects that does not have any RSS - you can create RSS feeds for project news in Yahoo! Pipes.
Also seek for tools that create RSS feed entries when page contents change.
Cheers! :)
These guys have what you need.
The Ohloh API is a free, REST-based programming interface to the Ohloh open source directory. You can use the Ohloh API to create your own applications and web services based on Ohloh data.
