Writing, writing and writing

I have found another Web site to write articles for.  Meanwhile, I have also encourage my 18 year-old son to write for it as well.  In the last two days he has applied for two job openings.  I've lost count on how many he's applied for.  He has not been called for one interview, even after making follow-up calls.  Because the managers are getting upset with people you call back, he has resorted focusing on applying and hoping for the best.
