If I post tips I dont feel any pressure at all because I don't expect anyone to use them unless after a period of time they decide they are worth while.
I also have the choice to post or not post as I see fit.
I would feel pressure if i was being paid to post.
I think it's all about gaining some acceptance among forumites and the comeraderie that it might bring because I have found by and large that the life of a punter can be a lonely one.
There are plenty of hobby punters about but not many serious or educated ones.
(in my area anyway)
