I think Lifehacker editors read a variety of blogs, so if you appear in one of those, you probably have a better chance of getting noticed. It's been a while, but probably smaller blogs that are focused on new companies - KillerStartups, MakeUseOf, ProgrammableWeb, that sort of thing. You can also try emailing them (tips@lifehacker), but I imagine that they don't read all of those.
