UPDATE: What seem to work a couple days ago is still funky. I will continue to investigate. In the meantime, I suggest using the Categories tab to explore older posts if the page starts to go haywire.
If you tried to explore the site lately, you may have found things went a little crazy if you scrolled down very far. I think I have that fixed. You’ll now need to click on the “Older posts” button every couple of pages, but it should make the page much more stable.
