- "Common-man publishing" like blogs, wikis, and webpages do not provide any checks and balances that a professional writer, reporter, or journalist might have. Other than your own resources, you may not know if you're doing something wrong - illegal, defamatory, etc.
- The legal system is always at least one step behind the cutting edge of society - while there might be laws in place to stop journalists from publishing certain material, but do those same laws apply to electronic media?
There is a separate page for concerns about student blogging - there, the issues get cloudier because of the fact that schools serve in loco parentis, and occasionally need to take additional action against students who publish improper material.
