Or no clue what the question was...
I sorted the section programming questions on #replies and found out that 22 pages of the 703 has had no answer (0 replies). That is 3% (acceptable?) ...
I can guess, too: On a busy day the question drops off page 1 within hours. From then on it is "lost in the archives".
A useful feature (which doesn't use email) could be a button to click which shows recent posts, which have no replies.
an unread topics link for all except international
