Well hello there! :) I'm not actually a geologist, either. The science is interesting, but primarily my motivation is aesthetic. I make jewelry with stones which I sell on Etsy, and I sell mineral specimens on eBay, and generally consider rock formations to be natural sculpture. But I'm here because I like to also read slash and as you said about DW "the people in charge seem to care about privacy, and the fact that it's being run for its users and not for advertisers." Thanks for commenting!
