50 Top Science Blogs (“by working scientist as far as they can tell”) based on technorati rank from Nature. Including:

• Invasive Species Weblog
• Bootstrap Analysis
• Mixing Memory

Missing science blogs include:

• Inky Circus (they actually rank high enough so the working scientist qualification must have eliminated them)
• Curious Cat Science and Engineering Blog (we don’t rank high enough or meet the working scientist qualification 🙁 )
