I don't think it should be compared to Twitter. Buzz is more personal and better equipped for discussions and conversations, yes it does share some similarities with Twitter by the way it is consumed. Twitter for me has become like TV, its a semi-
interactive celeb-reality show. I interact with friends on Facebook.
At some point most people will check their email (who would use an @myspace.com or @facebook.com* for primary email?), for most of us it's some form of web based email. Google now offers a more interactive email service then any other web based email providers with the addition of Buzz.
Look at how MySpace (now a hub for comedians and bands) has fallen off. The average person doesn't bother with more then just Facebook, and only about 20% of my friends from Facebook view Twitter, never-mind post. I think 20% is being generous too. People won't be ready for another social app, they can't even handle the new layout in Facebook without panic, how many "I hate the new Facebook" messages have you seen over the years?
Slow and steady. Make sure the mobile platform is there to view and post with ease, and integrate Wave and Reader. Please don't abandon the project too early.
To answer my own question's and leave you with another question:
It's obvious to why its email based, they want more Gmail users. Ive used it ever since Hotmail and I've never turned back.
Facebook is still growing, this is a small speedbump for them. Google watched Facebook buy Friendfeed for 47.5M. Maybe Google thought that Facebook seen Friendfeed as a threat? I used Friendfeed to post updates to my Facebook, had to stop using it cause it would post into news feeds and was to much noise to let out, I only wanted it on my wall. Which Facebook needs to re-address that situation with to many app's spitting into my feed, we need more control/filters. Facebook is for the masses of people you do know. Following people on Buzz will be just a few people u want to hear about in the tech world, much like how my Friendfeed became and was never a threat to Facebook IMO.
Both Google and Facebook are taking back control of these activity streams, Why is this?
Feel free to discuss...
