Is the Fluther Topics cloud up to date?

Over on the right side of the main Fluther page (not for you mobile device users), there’s the list of hot Fluther topics. It would appear that “iPhone” is the hottest topic. It’s displayed larger and with a darker color font than all others.

However, when I dug a little deeper, I found that “love” clearly beats out “iPhone”. Mainly in that “love” returns 83 pages of questions versus only 77 pages for “iPhone”.

Is there some special sauce is the ranking algorithm besides raw count that determines a topic’s primacy in the cloud? Or is it just a static snapshot from long ago?
