We are slated to go into public beta in about 19 hours as I write. Are we ready for it?
I am concerned that the site is full of chestnuts — solutions to classic puzzles that are already all over the web. This makes a significant part of the site rather boring, which doesn't bode well for the site's success, and sets a dangerous precedent that it seems to establish the site as a chestnut repository.
So I think that we should extend the private beta and give us time to solve the puzzle dump problem.
First, we need to decide whether it is a problem. I think it is, but if the community disagrees, so be it. So far, the meta question doesn't have any highly-upvoted answer, showing that we as a community are still pondering the issue.
If we decide that it is a problem, we need to get rid of the puzzle dump questions. Ideally, edit them into something suitable, and edit the answers to match. If a question or an answer can't be made suitable, we should delete it before the site goes public.
