I suppose toadfrog might be drawing a distinction between people who pretty well only seem to post to these kinds of threads, and those who post a fair bit about music and other stuff as well.

When you click on the name at the top of a post (even a GUEST name), you get a page linking to all previous posts.

Omar Khayyám/Edward Fitzgerald was remarkably prescient about this sort of development:

The Moving Finger writes; and having writ,
Moves on: nor all they Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all they Tears wash out a Word of it.
