Update: It looks like the online Marketplace is now viewable as well.
Hey kids, remember the Xbox.com maintenance that went on earlier today? Oh, you say you were asleep. Well, it's not a big deal or anything, but we thought we would inform you that your Xbox.com profile page now displays your Avatar (assuming you have the NXE, of course). That's about it, really. As far as we can tell, the Xbox.com Marketplace still isn't open for business, so don't go thinking you can start blowing your Microsoft Points at work just yet. We expect that an any other major changes to Xbox.com will launch tomorrow alongside the NXE.
