Did something change?

Hi all! This week, I noticed a massive drop in my readership and also saw that several people I tagged also disappeared.

I'm wondering if something's changed on Clicky's side, or if my readers coincidentally changed something on their side or if this is all just an odd coincidence in general.

I read the blog entry where the tags would ultimately become useless; is that still the case and are my old tags essentially expired/useless?
