The tag cloud is the one that how much tag (word) is contained in the article is visually displayed.
It was assumed that this was better for SEO. (it’s long long ago? () I do not know now. )

However, regardless of SEO, I think it is interesting, because the reader can know summary of post at once by tag cloud.
However, if the writer doesn’t clearly write related tag, the tag cloud does not work very well.

If you want to work tag cloud very well, you must write clearly related tag at right side of editor.
