@theianfox. Thank you for the reference to da BBC site. I did have a look but think I need to spend more time on it.
@raincoaster. Sorry, I don't get it. I understand what you're saying about referencing other blogs - creating a virtual network of links but are blogs in themselves credible. I've always avoided referencing them - unless I'm clear that I'm referencing someone's opinion. Wrong????
Also, does anyone have opinions on About.com.
NB: I really thought that Wikipedia had a fairly rigorous approval process + clear sign-posting, if a post was not well-referenced. Obviously my research skills need to improve.
FYI: All this started 'cos someone from Europe posted that she'd been told people eat monkey brains in South Africa. I said they definitely didn't (and it inspired a section on South Africa in my blog). Then someone commented she heard da same thing 'bout people in China. I then found a reference on Wiki dat this Was True for parts of China. Then someone, a blogger who is from China responded to say absolutely, definitely Not True. The global power of blogging, hey. But who to believe??????????????
