Flower or Weed?

I just posted my first 2010 entry for "Flower or Weed" on Facebook.  I suspect it is weed--doesn't look like any of those nursery plants.  In addition, it is out of place.  If it were a flower, I'd transplant it to an appropriate site.  I would definately say weed, but it doesn't have any thorns or stickers, nor is it multiplying at an exponential rate.

Right now the vote on FB is that it is a weed.  Too bad.  I like the tiny flowers.
