Well, that’s probably the question everybody wants an answer to. The platform has lot’s of potential, looks good, feels very fast and… needs some killer features.
It’s the first platform I try that, to me, has the opportunity of combining personal and work “circles” into one account. Once it gets integrated with Google Apps for business purposes, the sky is the limit. This could really hurt other platforms! Microsoft of course will feel some pain but also other very valuable platforms like Yammer, Jive, … can get hurt by this. Of course also some apps in the marketplace will have a hard time surviving (Socialwok, …). As I’m thinking about it, Google+ could create a whole bunch of victims.
As for the pleasure use of it, Google should really integrate the more established tools out there. Thinking of Instagram, Foursquare (I know, they have Latitude but hey, 4sq is really cool), twitter, Tumblr (and blogger of course), etc.
My hopes are set high! Let’s see what happens in the next few months!
