Wandering electrons... but not too far

I'm reading an article in Smashing Magazine called "30 Usability Issues To Be Aware Of".

The author points out the "Baby duck syndrome":

Baby-Duck-Syndrome
Baby Duck Syndrome describes the tendency for visitors to stick to the first design they learn and judge other designs by their similarity to that first design. The result is that users generally prefer systems similar to those they learned on and dislike unfamiliar systems. This results in the usability problems most re-designs have: users, get used with previous designs, feel uncomfortable with new site structure they have to find their way through.

The subject in the article is webpage design, but ya can't help thinking of all those posts in the forum, you know, the ones that go something like this:

"I want blah blah blah blah blah like Firefox"
