I was aware that this was a theoretical possibility, but I had never
seen a site that did it and I wasn't sure how well browsers would cope
with constant updating of the URL bar like that or whether people
would like it. I'm certainly not sure if I would like it.

We track the location in a cookie so that if you reload the page, or
go away and come back within a browser session the location is preserved.

As somebody has already said, you can get a permalink from the View
tab and we have plans to improve that to make permalinks more obvious.
