That page hasn't aged all that well. The prediction that applications would need to switch to a new hash function "every few years" hasn't panned out. The feared improved attacks on SHA-2 have failed to materialize. Applications that chose SHA-2 20 years ago are still quite secure today.
It seems we just weren't very good at designing hash functions in the 90s.
