I’ve been meaning to write an article about a few of the communities in the open source world. However, I believe that the article “7 Open Source Projects to cut your teeth on (and the ones to avoid)” by Rikki of ITWorld has said what I wanted to. Some of the open source projects that I’ve had good/bad experiences contributing to have been:
Good:
- 
    Seafile – The guys that work on this project are freaking great! I can’t say enough good things about Seafile. 
Bad:
- 
    XBMC [They will not take bug reports or feature suggestions] 
- 
    Tiny-Tiny RSS 
- 
    OpenStack Folsom Install Guide [The official documentation doesn’t agree with some of the suggestions, and I’ve tried to point this out] 
I understand that these tend to be non-work projects, and that it can take a lot of work to maintain a community. But its rather frustrating that people who attempt to chip in to help make the system/application/code better are treated rather roughly.
