These days, though, I'm noticing that on more and more sites the tag clouds have evaporated. I'm not saying they're dead (okay, granted, that's exactly what the cartoon's saying, but that's why they issue artistic licenses), but they're getting scarcer.
I love tag clouds too. It was my favorite form of navigation on this blog. And that is exactly why I removed it. Where I loved my tag cloud no one else did. In reality, no one clicked on any of the non-contextual navigation. The only thing people were clicking on were links to other articles that appeared within posts: hyperlinks. The very foundation of the Web. Period.
So where the tag cloud is disappearing, so should all other forms of site navigation. They are not used and just get in the way. If people really looked at their metrics, and paid attention to what their readers were doing, they'd take a completely different view of all of the bloat appearing on a page. I did, and that is why this site now supports a minimalist design
There is one link on a page that can be justified, and that is the one that tells people who is behind the stuff they find there. Nothing else is really justifiable and it all can evaporate-- not just the tag cloud.
