I wish we had closed the Help documents to comments from the beginning, of course. The Help Center is definitely a work in progress. As Manton said, we didn’t delete comments, only hid them so they would not be confusing to someone who was looking for the basic info of the help document.
I did leave one article that had a long discussion (Automatic cross-posting to Twitter, Mastodon, and other services) and created a new version in the help, and one article about Own Your Gram (Copying photos to Micro.blog from Instagram) in case someone searches for that.
Most of the discussions were inactive for 10-12 months, and in many cases, the issues were resolved in software updates over the last year. If there was a question still hanging, I made a note, and will be forwarding those to help.
There isn’t an easy and clear way to preserve old discussions, as far as I know. If someone is interested in pulling up an old thread, let me know.
