There's a really odd bug in delicious.com. I am anal about tagging my bookmarks, and I was very unhappy to discover that I had 217 bookmarks and apparently only 216 had a fandom tag. I say apparently, because after doing a search, I found the errant story. And it does have tags - all three of the ones I generally put on a bookmark.
The story in question is

Sigh. It's probably not worth reporting - I just wanted to put it out there in case any of you ran across the same problem.
(Yes, I balance my checkbook down to the penny too.)
ETA: Huh, adding more bookmarks made the problem go away. Probably should have tried that in the first place.
