4 Letter Domain Names

Are they worth building a name around?

I recently found a 4-letter domain which I bought, since it was an acronym for a longer name (with some modifications) which I was looking for. I am pretty happy about it; however, my question is that is it worth making a name around a 4-letter domain for the sake of having a short TLD, as I am sure there are other odd combinations still out there?

Hmmm, four letter domain.

Is the domain brandable? Is it easy to pronounce? Are the letters during pronunciation easy to confuse. For example, is there an F that can be mistaken for an S when spoken over the phone. Surely a four letter domain is a great asset to have, especially in today's tight spaces. ;)

I don't think there are any confusing letters, at least not in the one I bought! tee hee ;)

I still can't believe that I was able to find a pretty decent acronym like that. I know of at least one other 4 letter .com domain that is available for registeration, if anyone is interested in registering it, sticky me.

Note: I am not selling anything, just want to give another WebmasterWorld memeber the chance to register it before it's gone.
