It's (part of) what I do.
And I make plenty of money doing it (both buying and selling) as well as consulting for people who you have heard of and who you trust and that pay me for my opinion.
So given that we are talking about +-$12 or so for wdwee.com while you may not feel you need it there really isn't much in going with the expert opinion on the subject.
I mean if I decided to do standup comedy and you told me to "drink 3 glasses of water and piss before going on stage" I'd probably take your word for it and not tell you "I really don't think I need to do that". And I'm guessing I'm probably better at domains than you are at comedy.
Agree that wdwee is hard to type. But so is a long domain name (chance of typos is greater with more letters, in general). Not saying you should use it instead of the ironic name but as an additional short acronym.
