Ad-hoc analysis of which organization do the most work in web standards.

Data from day-to-day was used to get a list of active authors in the last 8 weeks. Conclusions up front:

Independent contractors or otherwise unaffiliated people are large contributors.
Google and Mozilla are the top contributors among browser vendors, roughly equally split.
W3C staff do a lot of spec work.
Intel is the top non-browser vendor.
