Caveats: I made this year's count based upon the attendee
list, which tends to be more accurate than counting heads. (In 2005, I
counted heads during one of the headliner sessions.)
Women at Web 2.0: 18.12%
At last year's Web 2.0, women made up 17.65% of the audience. While this could be taken to mean that Web 2.0 has increased its reach across genders, this may also simply be a factor of the different counting methods. I'm also not sure what statistical error rate is in effect for 1225 data points. (Any stats hounds out there that want to comment?) Like this year's DEMOfall trip, the repeat visit to Web 2.0 enables me to compare apples to apples and look for trends. DEMOfall, however, showed a substantial increase in women's participation - from 14.67% in 2005 to 18.28% in 2006. Web 2.0 did not - but then again, Web 2.0 started from a higher baseline and had less relative improvement to make.
