The Twitter Haiku

Tweeting is good fun.
An exercise in control.
Somewhat like haiku.

Am I the only one who can do this? Rattle off a poem, rhyming couplets or poetry on a dime? Is it weird or what? And is it why I don't really care for poetry -- because it comes to me easily? This is an interesting question. I have never been able to write a limerick, and I do like those (Get your minds out of Nantucket!) :-)
