Tags Suggest: Dynamic tag clouds
 

In the ever revolving world of data and trending topics I think a cool feature would be to have a "hot tag cloud" option.

The hot tag cloud could replace the standard tag cloud and give more weight to newer tags that are used more frequently (say over a 72 hour period) and then less weight to the older ones.


For ex:
You have a total of 500 thread tags:

You have 300 identical thread tags* and all 300 of them are 5 days old and haven't been used since. These would appear smaller.

You have 200 identical tags* used within the last 72 hours* these would appear larger than the ones not currently being used.
