I was looking for the appropriate place to post my iPhone question, so presumably I was looking for something like apple/ios.stack. I didn't find it in the list of sites, I posted my question to superuser, and guess what: a moderator moved it to apple.stack. Am I just blind or do some sites not show up on the list? What other sites might I be missing?
Also, a commenter on my question suggested me to post to stackexchange.com. I might be misinterpreting him, but I wasn't aware you could post there. I thought it was more of a directory site.
