I think it'd be a good idea for a 'domainer' - or someone with a fair bit of knowledge about the domain name market - to write a 'self-appraisal' sticky, or a FAQ about the value of domains.

Most domains posted for appraisal are worth reg fee; usually due to the fact they're just [keyword][random word].

I think this would really cut down on the number of appraisal threads.
