Mostly, the link should actually be enough, but this won't well for HTML scraped pages. And arguably not for NNTP news feeds.
We should just be able to use the guid (as we make one up for scraped pages and for we should be using the article id or sim for news feeds). It'd make the code easier to understand (note: probably need to address #320 before we do this!)
A note: ISTR there is actually one news feed that always produces the same URL for all the headlines. Probably want to check on, though given it does that, it's going to be quite hard to sensibly view old headlines anyway.
