I think of WordPress’s tags as free association. I try to just start thinking of related things and type as many in a short period as I can. And I’ll often go back and type more in later. I know this isn’t a great system, but I figure over time I can build enough of a tag library that I can start reusing terms.
But I didn’t realize they could have spaces in them. That’s right; if you’re using WordPress, you don’t need to limit your tags to URL safe characters. Give it a try.
I plan on updating my tags in the coming weeks to add spaces, capital letters and such. The tag “hall of shame” is much more appealing to me than “hallofshame.”
