The British Library
The most pretentious British URL:
Victoria and Albert Museum
Isn't it a museum, not a university? So what's the .ac.uk for?
How about http://vam.london.museum/ instead?
The most infuriating website:
Maybe there are videos I can watch here, but a three out of three failure rate didn't impress:
Copyrights restrict us from playing this video outside the U.S.
I wonder if anyone remembers what www stands for? It should now be usww.
Edited to fix first link as per comment below.
