Personally, my mousewheel is messed up so the only way I navigate pages is by auto-scrolling. When I click on a tag on the tag page and scroll down it loads a few posts at a time, maybe 20 or so then stops and I have to bump against the bottom of the page to load more. When I reach a certain number of posts (usually when it has loaded 20 more posts 9-10 times), it stops loading new posts entirely even if I scrol reaaallllyyy slowly.
In addition, using search and filtering by a tag only filters the 500 or so posts with that tag, it doesn't show 500 posts of that tag, which I assume is the cap for processing capacity reasons or something but it would be nice to have more search results than that, at least when you try filtering.
