Not sure my answer to #1 is relevant. I couldn't figure out what you meant by "tag index." I do see that tags on the top of posts are kind of messy. Eh. I actually haven't figured out the point of tags yet at all, to be honest. I haven't been paying attention. But your LJ is grand. Also, memories work fine for finding things, yes? I'm all confused and probably confusing. Ignore me!
