So I finally did what I should have done a long time ago, and dug into the code to figure out why Disqus was taking so long to load. I *think* the problem was the location of the code: Disqus was loading last after everything else on the page, which meant that if the Twitter widget was being fussy, all you saw on this end was that, hey, no Disqus! Drat! And so forth.
I *think* I have fixed this by repositioning the code. Let me know if something breaks, if the loading gets worse, or (happily) if I've maybe made things better.
UPDATE: I've also yanked out the Google Ads again because they were also taking forever to load.
UPDATE part two: I'm thinking about yanking the "Recent Rambles" (because it doesn't update in a timely manner and also takes time to load) and putting the "Hierarchical History" up there in its place. Speak now or forever hold, yada yada.
UPDATE part three: Ha-HA! I finally got a Current Comments widget that actually works and displays the commenter name again. Alas, we still don't have the "filter per thread" feature which was very nice and which I miss immensely, but at least we have something working now. In other news, Google is bad and they should feel bad.
