At work we use a homemade bug tracking system I built a couple years ago during a slow month. Although the code isn’t exactly stellar, it works pretty well and most importantly, people actually use it(!). My biggest beef with it (and all our internal web-based applications) is that every time I want to use the application, you have to login. It might be ok if I only used it once a day, but it’s something that I want to see immediately. Multiple times throughout the day someone will say “hey, what’s the status on issue #14044?” so after falling in love with SharpReader this week, I created an RSS feed for each project. Now I can keep SharpReader open in the system tray, it’ll automatically refresh the data every n minutes, and I don’t have to login each time to view the bugs.
I mention it because I think it’s one of those examples of an application being used for something that wasn’t originally intended by their creators. Luke Hutteman, who created SharpReader, probably never imagined that his 3 paned aggregator would be used to view tickets in a bug tracking system. What other ways are you using RSS?
