Hi Kel,
I had this same issue until I went to check my tags. Go to Posts and then to the Tags submenu. You will then see a listing of your tags and the number of posts that are attached to them. On mine, I see the number “1” listed for each post. So when I run show the Tag Cloud, all of the Tags will be one size, since none of them are greater than 1.
Test it for yourself like I did. Try adding one of your tags to a different post and let me know if the Tag Cloud changes. I think for full effectiveness, we need to go through our posts and add as many tags as possible, so long as they have relevance within the post.
Hope this helps.
