That's a lot of why Facebook is only barely profitable, whereas Google was making a killing when it had their traffic levels.
In the AOL sense, or in the Walmart sense? I thought the latest reporting still suggested that there isn't positive return for any of Facebook's investors yet.
ROI for investors will have to wait for a bit I think, given the sum of money involved. Still, I found it quite surprising that they were already in the black.
Based on my usage, HN would be #3 or 4 website worldwide.
There are lots of small businesses out there making total assloads of money that you never hear of because they do something like sell truck parts or specialty electronics. They buy their traffic off of Adwords, get ridiculous conversion rates, and average sales of $100+.
Party Poker used to make something like $1,000 per customer. So there'd be a ton of online poker/casino sties perhaps.
