I'm pleased to announce that the Home Library site is getting a facelift (admittedly, it only went up earlier today). This site will eventually get packed with lots of good stuff about the project, and this front page will always host the latest news about the project.
Right now, we're looking at one to two weeks before an initial release, since the core functionality just isn't quite there yet, but it's very close. It's usable, but there are some fairly critical components missing. I'm not going to release until those are there. You can always check out the road map for the project to see where we are, where we've been, and, most importantly, where we're going (particularly since right now the entire road's ahead of us).
