You know Jakob Nielsen's old saying "users don't scroll?" Maybe it's because you'd be violating his patent if you did. You got mail? Nope, that's also Jakob's patent. When was the last time this site updated? Again, don't ask or you could owe Jakob. Did I misspell anything in this post? Don't hit the spellcheck button, or it's violation time again. And that's just the tip of the scary patent iceberg. Is it a good idea for Jakob to have all these patents on basic internet application functions?
I usually just ignore Jakob - he has his right to his opinions, tho' I seldom agree with him - but I draw the line at misrepresenting a technology so egregiously... Acrobat's not that hard to understand; I can't believe it's possible for Neilsen to not know that the features he berates Acrobat for missing are, in actuality, right there to be used.
