"Only works with HTTP" -- that's why were are careful to make our
protocols only use HTTP.  That's like saying that talking as a means
of communication only works if both parties share a common language.
Sure, but that doesn't make it not useful!

It's not a cheat sheet: it's a list of cached content.  If your
activities are coming from lots of different sources, then your update
URLs will be different.  What's wrong with that?  It would actually be
a serious bug (IMO) if they *couldn't* be all different.
