Yeah, AT managed to gather good non-spammy ratings somehow—even though I do sometimes suspect that certain high ratings are artificial, but those are isolated cases. The site also clearly prioritizes open-source software, raising it even among higher-rated proprietary apps.

Since AT is crowdsourced, perhaps instead of discussing yet another list of alternatives, fellow HNers could go upvote software that they already use. Though this does require registration, of course.
