Not to worry, after looking at various sites that estimate worth, it seems it could conceivably go for $3500 on the low end to as high as $25k. I would "settle" for ~$8k I think.
Seriously, I don't know how these sites can estimate something like that. $25k??? How the heck could that even be possible? Even if they used page views as a guide, that's only because the content is free. If people had to pay for it, there would be FAR fewer visits.
