How much more valuable (percentage wise) are 4 letter names that legitimately stand for something (not necessarily a word) as opposed to 4 ramdon letters. Does the value come from the shortness or the fact it actually means something or combination of both. I found a good one and need to know if I should reg it.

Example: usmp.com could stand for United States Medical Professionals

Whereas: ytuq.com probably doesn't stand for anything. (although you could probably make something up)

An earlier post had 4 letter two word names (inbe.com & inby.com), common names, but no meaning.

Where do we stand on this?
