Are you still playing Diablo III? I don't play it as much as I used to, but I log on from time to time. Thankfully, Blizzard is still at work bringing us updates, the latest of which is an online character profile tool.
Just log into your Battle.net account, select your BattleTag, and select "view profile." Once you're there, you can view your skills, stats, gear, and pretty much everything else, just like Blizzard already allows for World of Warcraft. This'll make it much easier to see how far your friends have progressed while you're at work, when you're unable to log into Diablo III to check using the game's interface. I don't think it's a killer update, but it's something.
I think once the PVP patch hits (and whatever secret content Blizzard says they have planned), some people will head back to Diablo III.
