Bar Graphs aren't good for visualizing landscapes. Pie Charts aren't good for understanding physics.<p>It's a visualization. It's good for certain things. It's bad for others. I have seen tag clouds used very well, for example here:<p><a href="http://chir.ag/phernalia/preztags/">http://chir.ag/phernalia/preztags/</a>
I tend to agree with the author, and I find tag clouds too cluttered. Some might argue that it's a good way to see what the web site/blog is about, but sure there must be a better way to do that. If my blog is mostly about, say, technology then you can easily see that from the blog name, tag line, or the titles of the top two posts. I cannot see why tag clouds got so popular!!! Am I missing something?
