the crowd on google+ sort of reminds me of friendfeed.... (e.g. the people who reply to each others posts)
2 plus ones
Prasanna Srikhanta: it's a form of cross promotion
Sam Ho: Yea I was thinking something similar. People definitely seem to be more conversational initially. I think it might be due to both initial adoption and a more limited amount of friends (that are more tech oriented or early adopters).
My guess is that this is likely to change over time as people get more friends and are more hesitant to share as much to a wider group. (And people will post less and with a wider distribution you may have less conversation-inducing posts).
Elad Gil: yeah. maybe it is also a lot of the early FF crowd were all googlers...
