Callers Flood Indonesian President's Mobile Number President Abraham Lincoln held office hours and spoke to anybody who showed up. But it didn't work so well when Indonesia's new president tried the modern equivalent. Susilo Bambang Yudhoyono publicized his cell phone number last weekend. He said anybody could call or send text messages to complain about government services. People soon complained about the phone service. The presidential phone was clogged with thousands of messages, and can't be used anymore.
