First impressions of Diaspora!
Google+ looks a lot like Diaspora (I’m saying so because Diaspora has been on the development for a very,very long time,even before Google+ came out.)
Diaspora team should definitely look into upgrading their servers because right now, the network seems to lag a lot.
The Diaspora team has taken a lot of concepts from other social networks and combined them into one. The fact that the Diaspora is open source is a great thing because developers around the world can learn a lot from the Diaspora project
These are my impressions after 5 minutes of being in Diaspora.(More than that 5 minutes was spent actually, but then server lags are not supposed to be taken into account as actual timing)
