Why can't we see the tag distribution in our favorites?

That left column thing that's usually there while browsing that usually shows you what the most common tags are in the current search...

Why don't we see it when browsing our own favorites? It'd be interesting to see how my "interests" are split up sometimes.

It's computationally expensive is my guess. Particularly so in metatags, which aren't computed the same way regular tags are. This is not the only featured that'd be culled because of being too expensive. But of course only albert can tell you that for sure.

That's a shame. I wouldn't think of it being any harder on the server than normal tags, but I guess there's something else going on here.
