Over the last few weeks, I've been streamlining the community activities I'm involved in, in part because I'm just simply burned out. It really took the World Trade Center bombing to realize how tired I was of hatred in all forms, including racism, sexism, etc. Unfortunately, there's a lot of childishness in the Linux community, in part because of a lot of extreme geeks are poorly socialized (i.e. it's often out of ignorance).
I've decided that the reason is irrelevant: I'm tired of the energy expenditure right now. I'm on a job that's physically exhausting (but rewarding in its ways) and I feel better, overall, than I've felt in years.
