One Does Not Simply Tweet Forth a New Job

I really dig social networks - esp Twitter. But I think it's silly when I hear someone say, "If you need a job, you need to get on Twitter." It doesn't happen overnight. Ok, rarely, if ever, does it happen overnight. 

Why?  Because "One does not simply tweet forth a new job." 

Getting a job takes work - and the work starts before one needs a job.
