"then" for "than" being perhaps the most common confusion in Audiogon posts
Together with advise/advice, and lose/loose.
I can't quite get to 10 either, after everything else that has been said, but here are a half dozen, in no particular order:
1)The ability to quickly create a short list of products to consider in whatever category and price range I am looking to purchase, by researching member comments (and heavily filtering them based on my accumulated perceptions of the members' strong points and weak points).
2) The technical aspects of power distribution, grounding, and shielding (even though I am an experienced electrical engineer). Special thanks to Jea48.
3)About room equalization, subwoofer integration, and some of the subtleties of speaker design. Special thanks to Shadorne.
4)Lots of good things about amplifier design. Special thanks to Atmasphere, Steve McCormack, and Charles Hansen among others.
5) How satisfying it can be to help someone I don't know solve a frustrating technical problem.
6)Everything that Entrope and Elizabeth said, which I guess means that I'm "good at sorting out the bs." :)
