It's not just forum postings, I've noticed that Kotaku -- like 1Up and many, many other gaming blogs -- are still Not Quite Ready for Prime Time as media sites. Sometimes they may have interesting news, but all too many editors, writers and contributors have no sense of game history, or concentrate in a narrow field or genre, or just don't have enough grounding in the history of film, TV, painting, theater, literature to say intelligent things about videogames. Games aren't toys anymore, they are a full-fledged art-form, as complicated as TV and movies.
I just watched some editors from 1UP doing an interview with the composer for FF12, and it was painfully obvious they had no clue what questions to ask. Here's one of the most creative people in the industry, and they could only mumble "What's your inspiration" and "Who are you working with these days". Game journalism really needs to catch up to where the industry is.
