Whether race/sexuality/culture influences one's interests actively or passively I don't know, but generally a set of one peoples' most common interests differs from the set of another peoples' common interests. It's been my experience that all it takes for me to click with someone of another creed is to share a common interest. It seems too basic or obvious, but I think the mind needs just that push of familiarity to break down most, if not all, barriers.

Why did you leave? Please be detailed, I'm wondering why individuals are choosing to leave, not reasons the collective has.

I have no way to prove this, so you'll have to believe me on this one-- My "Theory of Knowledge" class in high school did this puzzle, and the first two to get the answer confidently both ended up in college for computer science. Pretty interesting-- you've learned with computer science, and others who have it, whether "it" is talent or whatever, appear drawn to fields where it's applicable.

I'm a new Atom user, and I'm loving it, but oh my god do I miss the css editing of Brackets. Sometimes on a large project I go back to brackets just so I can handle CSS across multiple files.

Maybe lucky for you, Atom has a package called 'vim-mode' that does exactly what it sounds like. While still keeping tree view, and the nice look and all. I have a friend that uses it (not much of a vim aficionado myself...) and he loves it.
