there are roughly 1000 meetup groups right? If 10% of them are active enough for a portion of the list, and if they are working on 1000 names each, then that would be roughly 100,000 names distributed.
I will have to ask Bryce again for a better estimate than that.
It's true Alice. but the best thing to do is make it short and sweet, hit a few of the BEST things you know, and then direct them to the official website. I hate reading long letters from people I don't know. If it's short, and GRABS my attention, I will focus on it and reach for more on my own.
A Slim Jim is a good idea!
