The TPB does certainly seem to consider if there is significant public opposition to a project. Good examples of this can be found at Long Valley and Nam Sang Wai. I think that this is probably more likely to succeed by producing a good reason for the rejection of a proposal (e.g. by giving information on why a site is important) rather than a simple 'I don't want this' type comment.
But you can be sure that TPB won't get the opportunity to listen to you if you don't comment on projects you don't agree with.
In light of attempted developments over the last year (Tai Long Wan, To Kwa Peng, etc.), I think it would be a good idea to pressure the government to actually think about what they want for land uses and decide on planning controls for the areas which are not currently covered (that would include Po Toi)
