The worst are the adds with a picture of some guy called Jimmy and another one with long hair. Both asking for money. It takes up the whole top of the page.
I agree and hence if it means more profit for Wikimedia organization, from people who do not use or do not know about adblock, then it is definitely a better choice than the current donation model.
they're the worst because they're the best. normal ads i can ignore. wikipedia's ads are not only visually hard to ignore, they're morally hard to ignore (and they don't go away after you donate)
