if I was the ruler of the universe...

...I'd make people stop using weird symbols in their delicious tags only to influence the sorting, or make them look pretty or whatever causes people to stick random symbols and brackets into their tags. That kind of thing just makes it harder to browse, subscribe and search by tag, and to generally find and use the bookmarks across the site (outside of one specific account where you see the sidebar, so it doesn't matter much that they randomly put some §, @, ', (, ~ into a tag to make it cryptic).

Even without it there are already significant variations, but if I want to look for say Kirk/Spock slash fic I can reasonably guess to try the tags "kirk/spock", "k/s", "spock/kirk", even "pairing:Kirk/spock" is not too bad, because that is relatively common syntax for those who like hierarchical tags. But sticking completeley random symbols in just sucks.

I realize the tag bundling interface on delicious is so broken that it is a pain to sort tags, so I get the impulse to just arrange tags in groups by putting symbols in. But that makes so many other things harder. *grumble*
