Most questions on Twitter go completely unanswered, say the founders of InboxQ, a service that helps business owners connect with potential customers over the social network.

The Internet tool, which is easy to get (just go to the website and download it) and free, is able to sweep through twitter posts, find business-relevant questions from real people and send them trickling into an entrepreneur's web browser. Business owners who know what people are asking, can answer their questions, build up an online reputation and possibly gain new followers.

For example, a company that makes custom iPhone cases might want to search for questions containing the keywords "iPhone" and "case," while an author might search for users asking for recommendations for their next read. Similar products would just find the keywords and comments. And there isn't much that an entrepreneur can do with comments, other than, well, comment back.

Questions allow businesses to be useful. Just remember: nobody likes a Twitter spammer.
