Meh, I doubt it would bring me back. 90% of my friends are on FB and the lack of a limit (or one I've ever hit) is quite nice. I'm able to write out full sentences with much less ambiguity or "text-speak" and while FB isn't my favourite company ever I'm going to go where my friends are at the end of the day. I don't write pages and pages or even multiple paragraphs most of the time but 1-2 sentences is normally not enough to express a full thought and because of that Twitter just doesn't work for me.
