Be smart. Don't post information on any social-networking website that you feel is inappropriate. You want to keep certain bits of information private. If a social-networking website asks you to provide information that you aren't comfortable sharing, don't share it. If the website insists you share that information, don't use that service. It's as simple as that.

The Book Geek
Strengths: You love to read - obviously. But you've also got a lot of excellent traits. Besides being well read, you as a book geek are often a great conversationalist, creative, and good with words. You can parlay this into dating by engaging a woman [or man] in deep conversation instead of the excruciating small talk that she so often has to endure from normals. Find an interest of hers and draw on your knowledge to hold your own in a free exchange of ideas (and, hopefully, your phone number). Better yet, hit the library to deepen your knowledge of the topics she's into and then dazzle her with your expertise.
Weaknesses: If you're a bibliophile, your eyes will immediately dart to the bookcase when you walk into someone's home for the first time. You know you're not supposed to judge a book by its cover (as it were), but you can't help it. You're only human (unlike the protagonists of the Twilight box set you're casting your judgey glance on). Instead of treating someone's taste in reading matter (or lack thereof) as a red flag, use it as a jumping-off point to ask questions that go deeper than the usual get-to-know-you fare. Hey, maybe there's some redeeming value to the Twilight series that you've overlooked. (Spoiler: There's not)
Special abilities: Curator +1, Empathic sensor +2, Wide-open mind +3.
