Thanks to Inbal Baron for adding me :)
Some notes:
- Getting started is easy. Just go over EVERYONE you've ever mail anything from your gmail, and add whoever you choose to the appropriate circle. The problem: If I could do the same with my facebook contacts, transition would be a lot easier.
- The concept is a mix between twitter and facebook. Seems like they've tried taking the best of both worlds. That's quite cool.
- The network is not working well on iPad. That's deliberate. Everybody knows you can't do rich text editing via iframe in tablets. So you have to use the 'mobile' web client for iPad, which is lame. It sucks.
- You'd think that after the buzz flop, google are going to be extra careful about privacy, people still don't trust google. We'll see how that evolves.
- The new Google toolbar looks EXACTLY like Twitter's. This is no coincidence.
And, final comment about this - This is not THE next big thing, sorry. My assumption is that the next big thing will not only be social, but physical as well.
