There was a big spaz-out over the University of Birmingham logo what with petitions and what-not because people thought they were abandoning the crest when they went to modify it. Turns out they didn't, and I personally didn't care that much.
The dolphin made it look cheaper and not like it was part of the Russell group... more polytechnic like, almost.
nb - I have no idea whether southhampton is any good, just commenting on the logo.
