In my very humble opinion, **who** tagged a resource with ctag T at time t could also be a very useful information to store. I'm expecting that in the near future we will have rich user profiles, based on sets of semantic tags (semantic tagclouds, if you prefer). Communities of interest, not just individual people, could also be defined in terms of such semantic cIouds. I think lots of interesting computations could be done over that kind of information: personalised reading recommendations obviously, but also relativisation of the popularity of a tagset (and I agree the timestamp is useful for that) to a particular community of users. For this sort of thing, don't we need a "taggedBy" property?
