Super Bloggers

Michael Arrington's TechCrunch, a blog about new technologies and companies, pulls in $60,000 in ad revenue every month.

Nick Denton launched the gossip site Gawker back in 2002, along with the gadget blog Gizmodo. Gawker Media now runs 13 sites and is expected to bring in #4 million worth of ad revenue this year.

The wave of blog success stories is on the rise. Popsugar, Fark, Huffington Post, MetaFilter, and that's just the tip of the iceberg.

So what do these blog success stories have in common?
For one, they're catering to a niche market. Frequency is also a big part of it.
And undoubtedly, getting the scoop plays a part in it as well.
