There is value in e.g. a commercial reply to a set of problems or a question one tweets. If it doesn't clutter up the interface by e.g. being in a separate area, like on Google, I feel that could be potentially be pretty powerful. It's not spam because spam is both unsolicited and (mostly) untargeted. In this case, while I don't solicit the commercial tweet, I am clearly interested enough in a subject to be talking about it. If it doesn't hamper my user experience, I wouldn't mind Twitter implementing what Gabriel suggests.
