to watermark or not to watermark?

Photographers, what do you do? do you watermark all of your photos published on the internet? Every few months I read something like this and get a bit freaked out about people stealing my work for profit. And that doesn’t just include photography. It also includes writing. I would love to post fiction and poetry on this blog but am reluctant because of digital thievery (that’s a whole other can of worms, though).

So I come around to this question of whether I should watermark my images. On the one hand I dislike the way watermarks look. On the other hand, it might prevent others from using my stuff. Or will it?  Can people get around a watermark?

What do you think?
