I have a site that is to be organized using both categories and tags. Posts will be grouped based on tags. On the main page, I want to display the most recent posts from the three most recently used tags - so fetching the three most recently used tags is key. The three displayed posts just need to be (a) the most recently modified posts and (b) from unique tags (posts only have one tag each).
The other option would be to use a couple loops and a one post query while loop, checking for duplicate tags within the posts it's selecting, most recent down. I can't figure out exactly how I would do this, though, so the former option seems more logical.
Any help would be appreciated! Thanks in advance.
