While FT shows post counts and join dates, I think FT would be even better if it showed an indication of how interesting the user was to the rest of the FT community. The easiest way to measure a user's interestingness would be to count the number of replies to threads started by that user. Perhaps there could be a badge for posters who started threads that generated 100 replies, another badge for posters who started 1000-reply threads, another badge for 10,000 reply threads, etc? (The count would only include replies that met a certain minimum word count, so that "+1" and "Concession Accepted" replies would not count towards the total.)
I agree with the general sentiment here, but OP status seems like a pretty poor proxy for overall helpfulness/value to the community. Plenty of people add value not by starting threads, but rather by providing useful replies, maintaining wikis, etc. Others have suggested upthread the idea of liking or up/downvoting posts, which seems like a better metric.
