That's a pretty good site. I was thinking of something similar, to be honest. Seeing a competitor like that makes me pause. Their traffic numbers look good, but still fall behind sites like CareerBuilder, and, of course, Monster. I do note a recent spike in traffic numbers. Thanks, economy!
Hashjobs.com is a pretty cute rails app one guy threw together, I assume to show his Rails chops rather than as a startup. It's not mine, but was interesting enough to mention.
http://jobfeedr.com/ is another interesting one, I think I heard of it here. It's a modified WP blog...
Wow, Quantcast/Compete estimate their monthly users to be 6-9 million. Their AdSense account must be quite healthy. I wonder how they got granted access to the data from the first few sites they index.
CPM for a job site must be something really nice, at least $5. Perhaps they have around 50M pageviews per month, so that would make $250,000 / month. Maybe valuation should be about $15M? Indeed got $5M in funding, so that seems fine. Simplyhired got $17M, that does seem on the high side.
