Jason Calacanis lays it out:
If you are in the Internet industry and you don’t have time to blog about your product then you should quit. Go home, give up, and find another career. Your competitors are blogging about their products and talking to the market, and there is no way to compete if you don’t engage the discussion. So, by not blogging you basically are giving up and telling the market that you don’t care. That’s the honest truth.
Blog or die!
Refusing to blog today – particularly if you’re in a tech company – is just not a good business decision.
