I've always wondered what merging the concept of a tag cloud with something with structure would yield so today I am really happy to present it as part of TiddlyTagMindMap. The weightings are done on frequency alone but could easily be changed to read in other values eg. popularity, amount of comments etc..

I also wanted the tag cloud to serve as an informant for navigation - to tell me where topics of interest were as I navigated. So for example in the above graph, the nodes that stick out to the reader are the big ones. These are because I have written lots about them, and I hope that thus this prompts the reader to dive forever into that topic.

I think the result of this is much more useful then a standard tag cloud. From a personal point of view straight away I can see where the mess on my blog is and what I keep rambling about and what is important to me and I feel this is very powerful - a picture paints a thousand words.

I still have much more work to do however. One thing I feel that is important is the user has complete power. This user interface doesn't allow a user to re-arrange nodes - this is like telling someone they have to read 500 documents on a desk however they cannot move them and instead must rely on a computer to do the rearrangement for them. As I said though.
