They seem to cause an issue with my site, specifically on the back end with my host. I don't know exactly what the deal is, but it is spiking my resource usage. I got an error twice in the last post trying to include tags. I've since rebuilt the tag database and omitted the use of tags in that post, and things look to be running a little more smoothly.

Oddly enough, the tags are loading more quickly, too, in the blog back end...
