HN'ers have a hard enough time accepting:

   'more features' != 'more marketshare'

I would caution this making sure to note "it depends on the startup". If your industry pays attention to blogs it's very much worth devoting large amounts of effort to capturing this attention. I as much as the next programmer need the _focus on marketing_ mantra pounded into my head time and time again.
