I feel that this question was closed too hastily by a moderator as being too broad.
I realize that this site is in beta and the moderators want to keep a fairly tight rein on how the site develops. But part of that development involves the growth of an active group of community reviewers, and you need to be willing to let that happen.
In this particular case, I feel that it's very much a judgement call. While the overall topic is quite broad, the actual questions asked could be answered fairly succinctly, and the answers would make good material for the site.
I'm just saying that this question could have been left open for at least a day or two, to see what the community thought about it. Moderation doesn't need to be that heavy-handed.
