I’ve deleted tags and renamed categories many times over the years. I realize it’s not great for search engines that I do that, but I don’t really care. This is my site and I do what I want. :)
That said, I’m always looking for ways to make my tags or categories more meaningful and I have yet to figure out the best way to interlink the 1,300+ posts on this site. Most are rambling, some are meant to be helpful, and the rest are just posts about my day of writing.
The thing is, I’m still considering a move to static HTML for this blog, and if that happens, I don’t want four bazillion gillion tag pages to deal with. I’d mostly like the tag and archive pages to be a list of links with the post title and one short line of text under it, but that’s going to mean some coding in the WP theme. Those pages will have to be generated with a template of some kind because I’m sure not doing that by hand for 1,300+ links.
All that to say there could be changes coming to the site. You’ll know they’re here when you see them.
I’ve already started with a bit of it by adding a plugin that lists all the posts on the site by year. They’re in reverse order, pretty much just like my reading logs. That’s pretty nifty and I like it. I guarantee I’ll keep that even if I go static with the site. :)
