And did it do anything for you?
I used to buy a weekly link on a blog with 34 times less traffic than mashable. It was generally is a pack of maybe 10-20 other links. That sent me ~10,000-20,000 per week.
Other than SEO benefit, that's very disappointing.
All the same - you're right, the traffic was low. A lot of people had thought "we'd made it" from being "Mashed", but clearly, that was anything but the truth. Still, I'll take it.
