Have you ever vaguely remembered reading something on a Blogger blog and wanted to find it again, but you're not sure you know what to look for? You just think you'd recognize it if you see it?
Or maybe you've discovered an interesting blog that has a lot of posts, and you're not sure how to sift through them? And the blogger doesn't like tags or labels, for some reason?
Here's a trick that works on Blogger: add /view/flipcard after the URL.
Examples: GROGNARDIA, Sham's Grog 'n Blog, Jeff's Gameblog,
Blogger offers other views, too, but the flipcard view is the one that packs the most information into the smallest space. Doesn't work for all blogs: Playing D&D with Porn Stars has this feature disabled, for example. But I use the trick with my own blog from time to time to find stuff I vaguely remember writing.
