Here's the results:

== All persons responding ==

Total responses: 167
Use SVN only: 24 (14%)
Use SVN+ Git: 26 (16%)
Use Git Only: 115 (69%)
Other: 2 (1%)

== Only committers + reviewers ==

Total responses: 105
Use SVN only: 18 (17%)
Use SVN+ Git: 21 (20%)
Use Git Only: 65 (62%)
Other: 1 (1%)

== Only reviewers ==

Total responses: 48
Use SVN only: 12 (25%)
Use SVN+ Git: 13 (27%)
Use Git Only: 22 (45%)
Other: 1 (2%)

== Values of "other" responses ==

1 "git-svn"
1 "Commit queue + trac"

== Conclusions (assuming the sample is representative) ==

- More of the WebKit community uses Git than SVN to access the WebKit repository
- Quite a few people use both
- A significant proportion of the community uses SVN, and a significant fraction of those use it exclusively
- Reviewers (presumably longer-time, more experienced contributors) are more likely to use SVN than newer contributors
- Newer participants are particularly likely to use Git
