All great insight here - deffo think I've just not been blessed with the "poster's mindset" and can't be arsed to put in the man hours to get any good at it. Too easily distracted, not clever enough, no confidence in my own opinions - you're never going to be one of the big boys with that sort of mentality.
Definitely think the "post whatever bollocks you like, no one actually cares" style some of the more seasoned heads have advocated is the way forward for me - as evidenced by this very post.
