MySpace: Great Expectations?

Today, everyone is talking about how MySpace is not all it?? been cracked out to be. Rupert Murdoch appears to have just lowered the social-networking site?? revenue forecast for next year. It looks like advertisers aren?? lining up as fast as News Corp. had hoped. I wonder what?? going on: It seems a little premature to start lowering 2008 forecasts. Could it be that Mr. Murdoch is sensing a weakness in online advertising in general? That would be bad news not just for MySpace, but for all online properties.
