I'm not a big fan of top “n” lists. They generally lack any kind of metric, and end up with bizarre compromise choices. This “Top Agenda Setters 2008”, supposedly about “the top 50 most influential individuals in the worldwide technology and IT industries”, is no exception.
For example, Linus Torvalds is completely absent, with dear old RMS scraping in at number 30 – behind Ashley “whatever happened to him?” Highfield (number 7), Craig “Microsoft suit” Mundie (number 13), and Peter “reality TV guru” Bazalgette (number 24).
If a “reality TV guru” is regarded as “more influential” than the man who started the free software revolution, then give me Second Life every time...
