It doesn't bother me. When the repetitions start getting tiresome, I just leave the thread. I might return to it if something interesting is said again, in which case I just ignore all the dross and respond to the interesting bit. It's bound to happen. Shrug.
Re post at the bottom of pages, as someone has already said, you can adjust the number of posts that you have on a page, so what is the bottom of a page to one person may not be the bottom of the page for someone else. So that is actually an imaginary problem.
You can have an entire thread on one page if you want, or 100 posts, or twenty-five...
