The term "small" is not so cool. A founder is an ambitious person, so it doesn't say "i want to build a small business" even if in the end, it's likely it will build a SB. Therefore media coverage tends to focus on unicorn and vc-startups. Write article on "small business" is no so cool and entertainment.
That's why we need to find a new term if we want to make "small business great again". I would like to see more PR coverage for bootstrapped/small business instead of VC-startups.
