RE:Motivation? Dudeforever, Sorry, I don't understand why you want to ask a forum member about his/her motivation of posting? First of all, you won't get an answer that you'll fully believe. Secondly, that's an irrelevant question because one's subjective intention shouldn't be used for others to make investment decisions. Sharing factual information is what this kind of forum should serve.
Resonsible posters should also disclose any risks that he/she sees and that will be very helpful to less experienced retail investors.
From what I have observed, I believe Castling is a responsible forum contributor.
If you have seen otherwise, please point out which points in Castlings posts that are questionable.
