A short one-line "is this a good stock?" post is unlikely to get much response. Bulletin boards are about reciprocity. Like most things in life, with discussion forums, the more you put in, the more you'll get out of it. It's worth taking the time to explain your own thoughts on the stock or idea (even if they are only at an early stage). Give it a nice friendly and readable title, and a bit of substance. This gives people some context to your inquiry, and makes them aware through the quality of your thinking that you are someone who's worth engaging with.
The value in bulletin boards is also as much, if not more, in seeking out contrary perspectives than it is in getting "advice" from other investors. Advice from an anonymous source is unlikely to be of much value, not least since you won't always know the motives of the other poster.
In behavioural finance, it’s well known that people are twice as likely to seek information that confirms what they already believe as they are to consider evidence that would challenge those beliefs. Without realising it, we emphasise information which reinforces our view whilst tending to downplay, avoid or even ignore contradictory information. Embrace dissent!
