Proper use of <3 ?

So, I'm trying to catch up with all the net abbreviations and symbols, but I always seem to be one step behind...Can someone tell me if it sounds cool to say, I<3 BB, or is it better to add the <3 at the end of the sentence like I see a lot of people doing? Also, I take it it means heart, which I would assume means pretty much the same thing as love...If anyone has any good links, that would be cool too, but I'd rather hear your take on it.

The <3 acts like heart/love like you think. Sometimes people just add it at the end of sentences for no real reason.

Thanks, I find it cute, and at least all messageboards and sites accept it unlike the alt number ones that only seem to work in some places...
