So Google Pictures just launched and it’s smart! Basically, it allows me to post a picture of myself and to display pictures of contacts in both my mailbox and my Gtalk. It looks like Google Pictures can be set to indicate presence just like the AIM icon does on AOL Mail–if you see the picture, the person is live. It also seems that I can upload pictures and assign them to my contacts. Yep, this looks viral, fun, and like it will have lots of future hooks. It’s very Google to build a social network through applications and tools, right?
