Doing yearly stats, I can only go back to 2009 since older posts were purged from the database, and still I'm not sure how accurate 2009 are.
2010 post counts put Lister firmly in the lead. Josh is second.

Stats show in 2010, new posters really came on strong. Josh, Sylvan, Wonger, Jeremy, Shawnc & Gav_Eaton were all new to the top 10. Lister really turned it on, almost doubling his post count. I improved my posting, but not enough, dropping two spots. Most impressive is Peter's consistency, year to year posting only varying by 2 posts.
