Milwaukee Bucks forward Charlie Villanueva was back on his Twitter account Wednesday — safely before tipoff this time. Villanueva’s widely publicized experiment with posting to the popular social networking Web site during halftime of a big game has ended at the team’s request. But Villanueva still isn’t sure he did anything wrong. “I have my own personal opinion on it,” Villanueva said after Milwaukee’s 106-80 loss to Orlando Wednesday night. “I understand coaches and GMs and I respect them. I’m not going to go against them, but my own personal opinion is we do have time anyways.”
