Because hashbangs make URLs ugly, and giant hex strings make me sad.
Also, rather than IDs, could names be used, falling back on - or similar when there are duplicated names? Once again, /sections/4/details/5074 makes me sad.
To sum it up:
Makes me sad: /web/index.html#!/servers/f6d20f5a827fb55a91b4e6747bd19f81053b422c/sections/4/details/5074
Makes me happy: /web/Home_NAS/Music/Artist/Key_Sounds_Label
Same degree of precision in there, but far prettier.
