Love Facebook, but hate your friends' endless invitations to play Farmville? You might not like the social network's latest iPad update. According to the Facebook developer blog, the company is testing out a new sidebar that offers users in landscape mode a sampling of trending topics, videos and other content. Most of this data is fairly personalized -- consisting of upcoming birthdays, events, holidays and recently played games, but there's also a special section reserved for advertising "popular" Facebook games. Fortunately, you aren't guaranteed to see the latter element right away: the column's layout is out based on individual use. If you don't play Facebook games, you might not see advertisements for them.
