quoting both because what MordorMongo is posting is EXACTLY how to differentiate between "i don't know what i want," and "auction." as with a lot of "what do i do? how could this possibly work??" trading questions, the answer is that you don't live or die by One Big Trade. find good trading partners with smaller trades, especially cool "more experienced" guys/gals that live in distro-areas that have stuff you can't get and want (or go to breweries that you like). start trading with them, then when you happen to pick up the next BA founders release or something, PM your partners and say "i have X, any interest? send what you think i should want," or "what do you think i should want?" etc. if you don't know what you want, you really shouldn't be trading your beer on the "open market" to begin with. unless it's locals-for-locals.
