In the case of Ruby, the contrast between the early community pre-Rails and what came after is astounding. Partly comes down to the personality differences between Matz and DHH, I guess. I loved the community pre-2005 and had no interest in engaging with it afterward (although I used Rails for a few personal projects).

This example is one of the more striking cases and you could write a (light) novel on the history of how it changed.

You kind of had to be there for part of it, at least the early stuff though.
