A few years back, when I was working the raffle table to raise money for the local preschool, the preschool director was completely confused by all these dudes wearing TalkBeer shirts. I had already learned from her that she knitted in her free time, so I said, "Well, imagine if you were in an online community that spent hours and hours talking about how this spool of yarn was better/worse than last year's spool, how the yarn is better from this local sheep farm vs. that sheep farm, etc. Let's call this community TalkYarn. Basically, this is what TalkBeer is about.
Oh, and they're generous as hell and will donate thousands of dollars to your preschool."
