Is it safe/wise to post one's cell#?

I'm sure there's some way to set something up for people to be able to notify you by phone without actually releasing your cell #. I'm not too twitter savvy but I think you can set up text notifications for twitter accounts. You might still have the problem with people abusing it to send tons of messages, but at least it would be something easy to turn off without having to get a brand new cell #.
