/r/netsec remains a great community. /r/coding is low-traffic, but aggressively moderated and has good content/people. /r/web_design is a lot like a slightly more informal version of Hacker News. /r/webdev is very small, but hey, it might pick up. Then there are lots of specific communities you can sign up for depending on your religious beliefs that have various values... /r/emacs /r/vim /r/haskell etc. most of the language specific subreddits have decent traffic.
