Observations of a home business newbie....

Quite often whilst browsing through the comments on promotional blogs about various online biz opps / programs I see people asking questions like - are there programs like this available outside XYZ countries, are there any opportunities around which genuinely don't require any sort of start up fee, do you know of anything which doesn't require a credit card, can you really make a profit in your first week without spending a cent and so on ........  Invariably the blog owner assures the 'commenter' that 'no, there aren't any that s/he knows of.' Now I don't know if the authors of these blogs, who obviously have a vested interest in ensuring that as many people as possible who read their blogs and the associated comments sign up with their opportunity, genuinely think that there are no programs out there with those features people are asking about??  Or perhaps (way more likely) they're just taking the easy, and most beneficial for them, way out.  F
