For various reasons related to our WordPress trademark, we ask if you’re going to start a site about WordPress or related to it that you not use "WordPress" in the domain name. Try using "wp" instead, or another variation. We’re not lawyers, but very good ones tell us we have to do this to preserve our trademark. Also many users have told us they find it confusing.
How utterly lame, and also inconsistent for an open source project. This is one of the few times I feel a bit let down by WordPress.
This reminds me a little of the Firefox logo and name copyright farrago. In my view, you should be open or not. An open source project setting rules on what people can and can’t do with a bunch of letters in a certain order is plain daft, in my view.
I’m leaving WordPress for Good where it is for now.
