Has Facebook CEO Mark Zuckerberg been driven mad by envy? In his effort to redesign his social network in the image of Twitter, he may well end up destroying everything good about it, users say.

But as people get used to the latest changes, they're starting to realize that this redesign is simply, objectively bad.

Facebook actually introduced status updates before Twitter even launched, a fact few people now remember among the wave of Twitter hype. But the sites have long differed in their presentation of updates. Twitter shows all your friends' updates in an undifferentiated fashion; try to go back more than an hour or two, and you get lost in the noise. Until now, an algorithm has ruled Facebook's presentation of updates, so only the most interesting bits show up on a user's "news feed"; not all updates show up, but the vital ones do.
