As you can see, the right column of this page is actually full of stuff again. I decided to just deal with the Google Plus API as is, and instead of using their image URLs, I’m just locally caching all of the images (and thumbnails) and hosting them here, rather than linking to broken links.
It works decently, I suppose. Though I noticed that Plus is weird about what it considers to be the “title” of a given post - most of these don’t actually have titles, it’s just guessing. So they’re a little weird sometimes. Better than nothing though.
