The problem with attempting to write my own license is I don't know nearly enough legal stuff to do something like that. So the most likely (and worst) outcome that would come from that is the license not being legally valid at all and so people would stay away from using the code for that reason (because they wouldn't legally have permission).

I typically just stick with FreeBSD style licensing, though I don't really care about all the clauses but would still leave them in so people know right away what they have to agree to (as it's a common license much like GPL, MIT, etc.).

Personally i've stayed away from WTFPL myself, since I've yet to see how it copes with projects that have been adopted into other large commercial ones. The simplest license I like is beerware but again for the same reason as WTFPL I've never used it.
