At long last, thanks to the generosity and coding skill of Oliphantom Menace (@oliphant@oliphant.social), the archive of "toots" that were posted on my now defunct account on Mastodonbooks.net is now live, browseable, and searchable. Here is the link:

To search for text, a date posted, or something like that, use the Search link.
But even cooler is the Hashtag Word Cloud. Of course, #WritersCoffeeClub is the largest, but others are surprisingly frequent. Check it out!
