Can Google+ work for me?

I should start this with saying that I've only been reading about Google+. I do not currently have access to it.

I'm a heavy Google user.  I use many of their products. I like the integration and I like how their tools work for the most part (Google Docs is still a bit clunky).  So I'd be a prime candidate for Google+, their new social network, right?

Well the problem is that I don't have that many friends/associates that are using Google products that much.  A few sure, but it makes me wonder how is Google going to get people to migrate from Facebook and/or Twitter?  I don't use Facebook but I know only a few of the people I know who use Facebook will check out Google+, much less put any serious thought into switching.  I say switch because, how many people are going to maintain both?  Twitter and Facebook are different enough that they can have some cross over customers, but will Google+ have that?  Would people put up with three social networks?

It's way too early to say but Google will have to pull out some big guns to draw users away from Facebook and Twitter, or have some really awesome technology that allows it to live side by side with them.  I'm not saying it can't be done or won't happen, but I'm not holding my breath.

In the meantime I anxiously await my invite so I can evaluate it for myself.
