What would it cost to buy out slashdot, presuming it was running at a profit with a skeleton crew before it was sold to dice? Form a non profit, buy the site, rights, etc etc. $2 million? Is slashdot even worth that much? Would they take $300,000 in return for perpetual dice.com banner ads or something? Their tax lawyers would be able to write it off as a loss/capital gain and shareholders could swallow it due to the perpetual advertising presence. We could keep the existing staff and just turn it back in to the independent walled garden it was at one point.
If dice.com, an IT jobs site, could not turn a profit with this, and weren't able to monetize slashdot without destroying what little value it had, I doubt the market value is much more than 95% of the current ad revenue they're getting. These sorts of sites aren't really geared towards being sold to the highest bidder, as the community is ready to walk at any point so you're kind of stuck with the revenue it's already generating via banner ads.
Maybe they could just gift it to the community with the advertising condition? We all knew the buyout was a terrible idea, maybe it's time to just give back the site.
