Ruby on Rails -- actually a pretty good overview. Note, though, that the slide presentation pointed to was sanitized (the most graphic/offensive images stripped out) within a day or two of being posted.

Ruby on Rails: one of the first reaction posts

Ruby on Rails Railsbridge(post CouchDB mess) mission: "To create an inclusive and friendly Ruby on Rails community."

Thoughtful discussion on various aspects. "Women are a tiny minority in the Ruby world, and we know it. Even before someone says, “hey, it’s cool to see women working with Ruby”. (These sorts of comments are often heard as “holy cow, there’s a chick in this room.” It’s not an issue of intent. It’s that we already felt like we have a blinking arrow over our heads.)"

"I voted for it, actually, because CouchDB is one of those things that’s the new hotness and I haven’t had a chance to play with it, and besides, he wouldn’t actually put porn in the slides. Right? Well, once he figured out that it was a problem, he’d acknowledge the error and we could move on. Right? Well, surely the fearless leader of Rails wouldn’t actually condone it. ..."

Ruby On Rails presentation/dismissal reaction

Ruby on Rails: a reaction to some of the reaction

Ruby on Rails reaction reaction. "After all the consequence of a society that is tolerant of nastiness and bullying is one where only the thick-skinned need apply. I'd prefer that people are welcomed for their ability in software development, not their ability to withstand offense."

Ruby on Rails reaction reaction. Grace in social interactions, or the lack thereof.

Ruby on Rails later reaction. "Cultures which value diversity and collaboration over individual ego are required to cultivate an enticing environment. It’s difficult to attract a wide range of contributors if the environment is constantly abrasive."
