it is acceptable to pitch to bloggers about your site?
SamReidHughes: Should you bound your actions by what is acceptable, or should you bound your actions by what is practical and moral?  The question I would ask, to phrase your worries more explicitly, is to ask whether that behavior will make things better or worse for you (because if you ask me, there's nothing morally wrong about telling people about your site).  If the blogger were to say negative things about your site on his/her blog, in reaction to a politely worded message, people would react as if the blogger were whining, and your site would get free publicity.  If the blogger were to say positive things about your site, well that's certainly good.  If the blogger were to inform the cabal that you messaged them then they might organize an ignorance campaign.  So, do you believe in the blogger cabal? :-)
