Google Plussers +Paul Allen and +Danny Sullivan have seen their content shared on Techmeme frequently enough that both are listed on the Techmeme leaderboard, which tracks the most frequently carried sources on the site over the last 30 days.

I would not be surprised to see +Vic Gundotra and +Bradley Horowitz be listed at other times on this list in the future.
