I think it may have been Justin O'Donnell who tweeted something about Cointree, a site that makes it easy for people to send you cryptocurrency -- you put in your wallet addresses and when people visit your profile they can get a QR code, clickable link for opening their native wallet, or just plain address. You can change your addresses at will, but the profile link always remains the same, which is nice.
I've set up a Cointree profile for Rational Review News Digest, since we're running our year-end fundraiser (see the web edition for a pinned post on that). I haven't hit the cryptocurrency angle during the fundraiser yet, but when I do I'll flog the Cointree link.
An aside: Yes, I'm behind on my "at least one post a day" goal for this month, although I remain ahead of it for the year. I've been unusually busy, although I don't know why. I don't feel like I'm really doing any more than usual; I just feel like everything's taking longer than it should. I go through phases like that.
