Honestly, yes, and I do all the time. Not to register accounts, necessarily, but to view historical topics, of which there are hundreds that are interesting.

Aside from Bitcoin (obviously), many blockchain "firsts" happened here on this very forum.

As for your other points about most new posts being boring, you're absolutely right! I cannot argue against this point. However, there's still some interesting stuff going on in a few places, and I appreciate the camaraderie that I've developed with several others here over the years.
