We’ve now been on LibraryThing for twenty years! Very impressive.
I’ve noticed that it has been ten years since anyone other than me has posted in this group. I figure that it is time for me to do a grande finale posting to cover what I have been up to for all twenty of those years and then maybe leave it be. For those who are new to these posts and are curious how it all began, you can spend a half hour or so starting with this thread: https://www.librarything.com/topic/220596#n5530961 and then moving on to this one: https://www.librarything.com/topic/254092#n8801371 before finishing up here. With luck, I’ll get around to lots of analysis and stuff that I put off in previous years’ posts. But I want to at least get my traditional stats out there, more or less on the anniversary.
So here they are:

There are only minor changes there. I've dispensed with the asterisks, since there are now colored buttons indicating whether a library is very active, active, somewhat active, or inactive.
The change from last year’s most and least obscure follows are:
Lycanthropist: 9080/281/19
Sylphette: 1726/4671/654
As I said above, I’ll almost certainly have more to say about all of these in a while. I especially intend to look at the numbers over time, as I did at the fifteenth anniversary. But this is a start to the grand finale.
