Agree with panel rating?
Michael Arrington is the founder and editor of TechCrunch - an influential blog founded in June 2005 that profiles and reviews new internet products and companies.
Arrington has a "huge amount of power" in the entrepreneurial and venture capital community, according to one of the Agenda Setter panellists, and his inclusion in the top 50 shows the growing power of the blogging community.
As well as writing about start-ups, Arrington has done it himself. Before founding TechCrunch, Arrington spent time as a corporate attorney working with technology companies on IPOs and other financial transactions
After this he worked for start-up RealNames and later co-founded a company called Achex, which was later sold to First Data Corp for $32m.
