Mysteries of RSS

I have put my collection of local tech, PR, and marketing blogs Blogdigger and Technorati. Both feeds are supposed to have most recent posts float to the top. So why are there different results?

Why do they currently have different posts floating to the top? And why are some blogs favored over others? Clearly it has something to do with their RSS feeds; but what?

Congratulations Blogdigger!

Blogdigger Acquired by Odeo

I'm very happy to announce that Blogdigger has been acquired by Odeo. Over the last few months, I've been working with the folks at Odeo in incorporating Blogdigger's aggregation and search technology into Odeo's new beta site. Along with the acquisition, I've joined the new Odeo team as Vice President of Search and Engineering.

Congratulations Greg Gersh!
