Someone on the CPC Job Connections mailing list asked for some contacts at Symantec a few weeks. Although I only had cold contacts, I gave him my list. Just last week, he told me that, although he did not get a job there, he got someone to take a look at his resume due to my cold contact list. So, the moral of the story is: cold calling does allegedly work. It just hasn't worked for me thus far. ('Though, admittedly, I haven't pushed the envelope all the way.)
