I stumbled onto (yes, literally with the StumbleUpon toolbar) Blogburst today and was relatively impressed with their content partners. The idea is that you submit your blog and the content (if accepted) gets fed to large publishers like the Washington Post, San Francisco Chronicle, Houston Chronicle and San Antonio Express-News (and possibly others). I've signed up SEOmoz to give it a spin.

Does anyone have experience with this or other, similiar networks? Do you think the future involves major publishers leveraging blog content on their sites?

Oh, and, why, pray tell, is the Ladder Project one of their featured blogs? It's not terrible, but it looks like a list of newbie tips you'd find at an SEO forum, with little additional value (and taking doesn't have an "e" just for reference). Maybe I just read a few bad posts.
