You know - posts like this are just too open-ended to make me interested. Oh sure - there are dozens or even hundreds of people here on HN who just want to talk so you'll probably get responses. The rest of us - we look at a post like this and think, "If he/she was truly interested in getting suggestions, he/she would have put more info in the post. It's too generic as it is. Also, OP didn't bother listing any of his/her favorites. It's just comment/karma-bait."
