Cool! Haven't looked at the stuff in great detail, but one thing struck me:

I like the idea of using this as an additional similarity metric. 

So 'find items like X' could be 'find items with textual content similar to
X' or
'find more items which people have co-categorised with X". 

Or both. 

Or more refined versions of each (for the content based approach you could
have LSI techniques or trigrams etc, for the semantic based technique one
could have semantic distance along a taxonomy).

This is sort of what I'm doing in a project I call "semantic
classification".
