If you're still playing Diablo 3, you'll have plenty to be happy about, as Blizzard has just enabled Character Profiles. With the new Character Profiles, you'll be able to view your characters on the web.
You can view your heroes' gear, stats, and skills, and track their progress through the game. You can even share your build with your friends and allow them to look at what you have going on with each of your characters.
Likewisem you'll also be able to check out what your friends are doing with their characters, and compare notes on gear, skill & rune choices, and just about everything else.
Finally, the new system allows you to view what other players on the official Battle.net forums have as their characters.
Now that Blizzard's worked this whole thing out, perhaps we'll finally see the release of Patch 1.0.4 of the game.
