I was also mostly a lurker on reddit. I found that most comment sections were comprised of cynics and comedians (and, as you said, who ever can make the best pun). The way the karma system rewards these types of posts seems to drown out any real conversation that might of been going on. Hubski seems to me (in my short time here) to have a better structure to support real conversation. I hope that both you and I can grow to enjoy this site and be part of what seems to be an great community.
