Apologies to all of you Dixie Chicks fans for co-opting one of their song titles.
I've had this gnawing feeling for sometime that explicitly visible URLs are annoying, distracting, evil - and yet another sign of the bones of the Web sticking through. They should be banished from sight of the average user.
The growing use of Web services will accelerate this banishment, I suspect. When one app talks to another, as a user you really don't care how it does so, and thus touching a service will simply be part of the plumbing. Nowadays, that plumbing is overt, and you see it every time you enter an address in a browser or roll your cursor over a link and see the URL flash in your browser's status bar. Simple URLs are memorable (http://www.ibm.com) but most extended ones are ugly and meaningless to the average user.
No idea why I'm ranting about this nit today, except just to make a prediction that URLs will likely go the way of old telephone numbers, such as FLeetwood5-1273.
