There's only one thing that matters with Orkut in this stage of its evolution: Orkut's elegantly simple user interface. Technologists never seem to get it. Look at Blogger. Didn't matter that it was down a lot in the early days. Didn't matter that sometimes stuff didn't work, especially beta features. People came by the boatloads from the Internet land of the previously overlooked.
Blogger was and is push button simple, and that's what gets the most people playing online. Quick and easy gets the entire web lower and middle class every time.
Orkut's got that. Doesn't need anything else yet. Soon, but not yet.
There's so much more it can be.
Must make the social networks folks' fingers itch.
Makes me giggle.
