KungfuMike I guess is now best known in neckbeard circles for being the one who most capitalized on trading the early White Birch beers. As background, White Birch was possibly the first craft brewery to put bottle counts on the labels. They were pumped up heavy by locals and perhaps a few good early releases, but their QC was godawful. Infected, yes, but often worse. I seem to remember hearing about a few "mildew-y" releases. The main gripe is that people swapped good beer for what turned out to be .rar trash. The blowback on White Birch was so bad it's hard to believe they're still an active brewery, but I guess they turned things around..
Mikesgroove... where to begin? He was probaby *the* BeerAdvocate ticker of his time, save for maybe
northyorksammy, but definitely the most active trader. He became so well known that dudes were tripping over themselves to hook this guy up with whatever new release he casually expressed interest in, assuming he'd hook them up. If you were foolish enough to not negotiate and say, "just send what you think is fair" you were guaranteed to get a box of garbage: mostly extras he'd received in other trades that he already ticked, faded/expired IPA's, and oftentimes he'd send you beers from your home market. Really a product of what we'd find out later to be his compulsion to trade.
Cut to several years later: he's apparently lost his job but for nearly a year is still putting out what some have estimated at 10-20 boxes PER WEEK all without drawing an income but presumably paying his mortgage, bills, etc. He goes dark on BA and social media while owing a LOT of valuable beers to trade partners, but in back-channels he's selling the entirety of his cellar, including many newly received bottles AND what he was supposed to send out for them to. IIRC, he sold the lion's share to that Joel guy for $15k. Someone can correct me if I'm remembering wrong.
