Oftentimes, I forget to add the user's name when responding to a question I'm asked, and Aardvark interprets it as a new question from me. (Sometimes, this is because I took a long time to answer.) Aardvark should have better detection to determine if I'm actually asking a question. (The lack of a question mark could be a good indicator!) This could also tie in nicely with the suggested feature of being able to indicate when a question was answered.
