Commit graph there is wrong - I wrote I wiped out a part of its development history (whole 2007 year) during repository migration; in fact, all these changes must be shown as a single #0 revision, and thus there must be a peak at the first commit. But, by some reason, Ohloh shows this differently - may be because Mercurial support there is still in Beta.
ORMBattle.NET is also registered there. Its statistics seems fully correct, but much less impressive ;)
If you use one of these projects, please spend few minutes on registration there.
