Nobody likes a know-it-all, right? Well, unless they need to know something that know-it-all knows. And on the flip side, some people are just naturally helpful and want to offer advice—but unless your name is Miss Manners, you might not get asked.
Aardvark is a fun and free service that matches up question askers with confident answerers. It brands itself as a “social Q&A,” and it’s perfect for those times when you need a subjective opinion (“What’s the best Twitter app for iPhone?”) rather than an easily Google-able fact (“How much does Twitterific cost?”). Plus you get to give your two cents on other people’s queries while keeping your privacy intact.
