True. One interesting aspect of keeping the number of methods small is that
utilities can be built that operate on any number of sites and understand
how to avoid 'unsafe' operations. In the case of Flickr, if I used a
pre-fetching tool or client side spider/indexer, those images would be toast
without my knowing about it. Traversing a URI should be 'safe' - this opens
up new application possibilities.

Yes, and they shouldn't use GET to modify data.
