I sort of keep track of the ongoing status of some software by having the relevant website or blog or forum (or all of those) in my Bazqux RSS feed-reader. If the feed stops issuing new posts, then I can check to see whether it is moribund/gone away or just a temporary faltering. I can view the history (all the old posts) from a given feed as well - i.e., those posts that were captured by my reader from when I started subscribing to that feed.
