I didn't need the Fake Steve Jobs to tell me that blogging won't make you rich (though I'm comfortable). And while I do believe that blogging can help you find work, I understand from this ex-CNN head writer/senior producer that it can just as easily foreclose numerous career options.
Do you have a blog? Has it helped or hurt your job prospects? Even if it hasn't made you rich, is it worth reading by people who don't know you (yet)? Talk to me and I'll tell the world via this incredibly powerful communication platform!
I find my blog a hassle. It can stop opportunities - it is supposed to be casual, but if you get to job hunting don't you want that blog to be pretty perfect? I am not seeing success with the time on Twitter yet either. We will see. It seems to unorganized and random to me to get your anywhere.
