… experimenting with Mastodon addresses at the foot of the page! …

More precisely, at the foot of the post.

Compare with this morning's https://billboard.bsd.cafe/post/189, where the first two shares were below the opening post:

1. the first share appears as a boost by Mastodon ID @announcements@bsd.cafe at https://mastodon.bsd.cafe/@stefano@billboard.bsd.cafe/116373336660957859 in the BSD Cafe Announcements area
2. the second share, by @stefano@mastodon.bsd.cafe, is not visible to me at https://mastodon.bsd.cafe/@stefano/with_replies – I imagine that @stefano sees the share, as himself in Mastodon, as a mention.
