Most “average users” are locked into Facebook and aren’t willing to consider a new social tool until they hear about it from their friends. Since most of the people who are on Google+ so far are geeks, insiders, social media stars, journalists, and other people (Google admitted tonight they are only accepting people who have strong social graphs so that they can both make sure everyone has a good first experience as well as test out some of the technology before opening it up to a wider audience) the chances normal people (metaphorically speaking, your mom) won’t hear about Google+ from normal users for quite a while.
By then I’m sure Facebook will react (ie, copy) Google+’s best features (Facebook already has called a press conference for next week where they are going to announce something “awesome”). This will mean that normal users, who aren’t really going to get involved at this point in Google+’s life, won’t feel the need to switch.

So, what is Google+ for then?

It’s for us!

Come on now, we geeks and early adopters and social media gurus need a place to talk free of folks who think Justin Bieber is the second coming of Christ. That’s what we have in Google+ right now. Do we really want to mess that up?
