UI of Facebook

The UI is SOOOO BUGGY! I wish I could just... :| -_-

Rating the Facebook UI from a user's perspective is not fair. Facebook is an ad space provider. As such its UI is optimized for that role.
Facebook is making huge profit - so i guess their UI works fine...

@Oktokolo Exactly

@Oktokolo Even for that is bad.
Why 2/3 of my screen is filled with things that I don't use everyday? (Left "menu" and contacts at right)

They could make the feed bigger

(They also need to get more relevant ads, after I buy something, I won't buy another, I don't need to see ads of that thing for the rest of the month)
