I could be wrong, but from where I'm standing, it's just you. Most major web applications built today thrive on a large, active ecosystem of open-source tools.

I could be wrong, but from where I'm standing, it's just you. Most major web applications built today thrive on a large, active ecosystem of open-source tools. Rails, Django, Play and Compojure all require the active participation of a large community of interested developers to keep them thriving and healthy. The author of the linked tool, who is a good dude, himself has a notable open source track record. I don't see any of this going away anytime soon. I used to maintain the Ruby version of CruiseControl, the original open-source CI tool. There's plenty of room for everyone here.
