I would like to create a Tag Cloud to add to my blog. I looked at some outside resources but they create a tag cloud from your post, the one I tried wasn't very impressive and it took a while to load.
What I want to do is iterate though my blog posts, pull out the comma separated tags, check for duplicates and display the tags in various font sizes in the side bar. Of course in doing this right I would like to have validation at time of entry so that it would suggest existing tags for consistency and allow me to easily enter a new tag, have parameters to adjust size ranges for the display font and number of tags displayed. The tag link would go to a display that showed a listing of th posts containing the tag or to the post itself if only one post contained the tag and if I was on a category listing page it would only show the tags for posts in that category.
I was going to start on this but I thought I would ask to see if anyone had already invented the wheel for me
