as a final note, this doesn't just apply to xkidwell's post. If you have experience with a social network not listed in this thread or experience you would like to share with one that is listed, please do post that experience here. The reason is that long lists in threads generally become repetitive and do not lead to discussion. Everyone has their favorites, but unless you are willing to explain what draws you to something, it is little help to the next person.
; Sorry if you felt singled out on this.
