I am a "binge poster" and tend to stay away for some period of time due to my work and then show up and read the threads and then post. That has become a little difficult due to the non-paginated Recent Discussions tab. Josh has said he would create a paginated version of it and I am sure my activity level will become more normal then.
I think the site is much faster than before, though. That's a pretty big thing for me because I often use the site from airports with lousy internet connections and the previous version had sometimes become unusable.
