Early Tomato flowers

I planted some tomato starts a few weeks back, and because of the cold snap we've had they are still pretty short.  One of them has started to flower, and I was wondering if I should nip them off so it can focus on growing the actual plant.

Or should I let some early tomatos develop?

I would let it go. 

There are lots of folks that want to snip off all sorts of things from the tomato plant for all sorts of reasons, and I suspect that each thing adds some 2% or 10% in some way.  But I prefer the idea of letting the tomato take care of itself as much as possible.  If there is something wrong and you can step in to mend it, then by all means do so.  In this case, there is really nothing wrong.  Let it go.
