Wordpressdotcom added Infinite Scroll to blogs. I turned it off but it still has it when you want to see older posts. How much I hate it! I spend more time staring at a damn spinning wheel than seeing more posts when Search won't bring up what I need (due to not recalling an exact keyword). I wonder if this was the case with Etsy too? The only Infinite Scroll I've seen that works properly has been with Twitter. Even Bloglovin (which I use for RSS) has a one-second or so stutter that can be very annoying.
