I built and deployed Commentful July last year. It has done well since, I am happy for the fact that it has served its users well.
Commentful was acquired by Bloggy Network this January and they just rebuilt and released BlogFlux Commentful with added features and functionalities. Kudos !
Unfortunately, I donot have any statistics from 2006. This year Jan 2007 to March 2007, Commentful.com served 8853009 requests. Yes, 8.8 million requests. I am surprised myself by Commentful's performance, despite its size (here's a secret. The Commentful software was roughly above 100KB).
I love you Commentful. And I honestly miss you ;(
