Those are just the people who posted here that they like it, I frequently like things I don't comment on. I have a thread for Starfleet's USS-Vengeance, I don't expect everyone who likes it to post, nor do I expect the whole, or even a large portion of the community to like it.
Part of doing this kind of thing is ignoring the haters, and adding what the people who post real suggestions add. thats how you grow, and posting bitchy comments when someone tries to compliment you and tell you they like something you did is not going to help
