nfdude,
Thanks for checking out the site!
One thing that annoys me about our site within the ipad/safari browser is the right margin is a little off when viewing a post with images and the full image popups dont may much attention to the floating header so they tend to hide behind it a little. But other than that it looks alright. Those issues are on the todo list. We are contemplating an ipad App, I am just not sure of the demand just yet.
Regarding the samples... yea I agree with you. They are mostly there to showcase what an ad looks like. One of the cool things about our posting model is that you can limit who can see your posts based on their visibility (cuts down on spam but still allows massive visibility). The problem with that model is that you can have zip codes in the middle of nowhere that dont get a lot of posts and may not fall into the visibilities of other posts, so the site can look more empty than it actually is. So for those scenarios, the samples do a good job of highlighting the post views. The good news is that they are set on a sliding scale of 10 samples in each category/visibility... so as posts grow inside of a specific category/visibility, the samples will trail off... you can see that by looking at categories that have posts and those that may not, there will always be at least 10 posts, including the samples. So the little thing that annoys you will slowly trail off into oblivion.
As far as the encrypted cookies. yea. I can see your point. They are just the visibility and the current zip, so we did not think that the security of them justified even the tiny amount of milliseconds it takes to encrypt them. But its such a small change, so we'll go ahead and make that change.... just for your IP though.
Again, thanks for the feedback, I DO appreciate it! I hope you get a chance to enjoy the site a bit more.
