By far, the issue most often mentioned was looks.
(Looks was mentioned more as a positive than as a negative.)
The second most common issue mentioned was navigation.
(I count organization under navigation).
There was no big mention of functionality.
(I hope that was because most web sites are fairly functional.)

Other things worth discussing:
Metaphor
scenarios
consistency
No one mentioned them, perhaps in part because, to a user, they are more in the background.

Here are some other concepts mentioned recently in class:
Learnability
flexibility
robustness

Consider the Web sites listed, that you did not nominate.

Q1
Do any of them use a metaphor?
If yes, how does the metaphor help (or hinder) usability?
If no, does that say anything about metaphors?

Q2
Scenarios are not obvious in a final web page.
Do you see any evidence that scenarios were used in the design of any of these pages?
If you see no evidence, does that mean no scenarios were used?

Q3
Which of these websites has the best consistency?

Q4
Which of these web sites has the best learnability? Why?

Q5
Which of these sites has the best flexibility? Why?

Q6
Which of these sites has the best robustness? Why?

While your answers may be short, you should actually explore the web pages in order to give a thoughtful answer.
