I came across this question and wondered why it hasn't been closed. It seems to be both opinion based and too broad (two questions in the post). As a moderator in GIS.SE, I would not hesitate to close this question, even with the high number of up votes.
I understand that this site is still in beta and wondered if that is why it remains open. I think it's a good idea at this stage of a site to keep questions open until the site graduates from beta. Once that happens I think the past should be closed until it is narrowed down.
I do feel that people need to get into the habit of not posting opinion based questions and limiting to one question per post. Perhaps we need to educate people on how the site works.
It's this the general consensus?
