Your thoughts on Google I/O?

Hey guys,

I'm just wondering what you think about Google's announcements at Google I/O. The conference just ended and they've shown some pretty cool stuff.

Google + looks really great. I feel like it is a Facebook killer for sure if only they could get people to migrate from the Facebook ecosystem, which seems to be a monumental task.

The hangouts looks like a really slick communication service. It's not the first but it looks great. Again, they have to figure out how to get people on it.

The new things they're doing with Google Maps look super exciting. The ability to view monuments in 3D was most attractive to me.

What are your thoughts?
