Welcome, is this thing on?

I've been noticing now that more replies have been left to discussion threads that pages load pretty slowly. When I click "Show more" I get brought back up to the top of the page and have to scroll back down, which is not ideal when I'm going through 100+ replies and only 5-10 are loading at a time. To accommodate longer threads it would be nice to have a "Show all replies" option next to the "Show more", or paginate the replies. Also consider a button that displays only my replies and people who have replied directly to me. Having buttons to reduce scrolling would be nice too, like "Top" and "Bottom" that will take me directly to those locations on the page.
