have the discussion lists I have followed for years - SIGCHI and STC
Usability - been abandoned in favor of IxDA? I have all my professional
discussions filtered into one folder, to read when I have time, and notice a
dramatic drop in postings from the two I mention. The names of those who
post, however, has changed much less.
I assume most of us have limited time to read and write discussion posts, so
it make sense to focus on a forum that gives the most bang for the buck.
