On the question of forum names, this was the first internet forum I joinedand at the time it appeared that nearly everyone used an alias or nickname and I followed suit. D-Type just seemed a good idea reflecting when I first became interested in the sport. Later, after a similar discussion to this I considered asking the administrators if I could change my user name, but by then my "D-Type" ID was well-established and used on other forums. So I compromised and put my name into my signature.
On the lists issue, the first question is whether a "list" feature is a valid journalistic device to provide a peg to hang an article on or whether it is just lazy journalism. It really depends on the subject of the list. Is it a sensible choice of list? Do I agree with the selection? Do I agree with the ranking? Does producing a list automatically imply a ranking? It probably does unless qualified by "In no particular order" or "in chronological order". There is a world of difference between the normal internet forum "What is your list of [say] 'Your favourite corners' and 'Your favourite corners and why'. . The "and why" is the journalist's justification.
As to standards of writing on forums. We all make typos and we should proof read before we post - but we don't. I am fairly relaxed about an enthusiast making a contribution expressing an opinion or giving us his reminiscences. But I do still expect factual accuracy. If someone claims to be a writer or journalist I expect a better standard: correct spelling, correct grammar, correct word usage, factual accuracy and clarity of meaning as a minimum.
