To Google+ or not to Google+...that be the question.  Ok, I'm a tad bit lost here.  Can anyone comment here as to what the think of Google+. 

I really don't understand this Google+ so:

Will it help me get more hits on my blogs?

If yes, how will it do that?

Is there anything I should be concerned about, ie bugs, problems or Google giving out to much info?

Appreciate any direction anyone can offer.
