As a reader of other people's blogs, I don't use their tag clouds. I just don't find it useful except a signal what the main scope of the blog MIGHT be. But that could be misleading also.
Also when the cloud gets too jammed with different tag keywords, I scarcely find it useful at all --from the standpoint of clickability.
As you can tell, I opted not to use a tag cloud. Especially on a company/business blog.
The blog I need help with is thirdwavecyclingblog.wordpress.com.
