I'm a big fan of the Tag Cloud widget that comes with WordPress, but would like to customize it so it only creates a cloud from the tags used in the most recent posts, say the last 30 to 60 days. This is important, because tags that were popular on my blog years ago still show up as the most popular today. I'd rather the tag cloud reflect recent post trends instead.
Is this possible? I've searched through the available plugins, but this does not seem to be an option on any of them.
