On Team Social we tracked issues in the simplest way possible: we made lists. As programmers fixed them, we crossed them off. It was easy to see how many were fixed and how many were left, or to add comments to a particular issue. Where it failed was triage: all bugs tended to be treated equally. Important issues, trivial issues, challenging bugs, and easy fixes were all listed in the same way. The common designations of priority (Is this priority 1, 2 or 3?) and severity (Are we deleting customers' blog posts, or did we just misspell something?) didn't exist.
