One very good test on brandability for a LLLL that i do all the time is 'name rememberance test'. If I look at an LLLL.com and can remember it 2 days from the last time I looked at it. Then it is a good name.
That's one thing I look for in a LLLL.com as a developer... something that can be remembered.
So what do I think about 'YOYF.com'? I'll let you know in 2 days.
But so far, I think i'll be able to recall it. Selling it to a reseller? I'd figure around 30-60 because of the majority perception of such a name right now in a reseller market. For someone that is willing to develop it? You'll find that you'll get more than average it's developer's worth due to the name rememberance factor.
