--- yes, but you also have the situation where you have two different
email addresses and it is the same entity.

--- OK, now this makes more sense. Yes, there are several ways to get
around this. One would be to ignore it in the results if it was part
of a tag cloud. Also, if they are publishing hAtom, you could do the
inverse and only look at the rel-tags inside an hEntry. Finally, you
might be able to apple some sort of normalizing algorthim to the data
set. If every page had the same 15 tags, plus X more, you could drop
the 15 from every entry thus removing the influence of the tag cloud
on each page.

--- well, one way to proposed to show weight was multiple <em>
elements around a rel-tag. This gives literally, more emphasis to it.
There has been discussions in the past if this is an abuse of
semantics or not. But the bigger issue is that you might have weighted
it with 2 <em> on a blog post two years ago, but now you are much more
interested so you weight it with 6 <em>. Are you going to go back and
change other values? If the weight is site-wide then you probably need
to have some sort of internal consistency.

We should capture more of these ideas on the wiki so future mailing
list questions can be pointed there rather than over several email
