You give an example of requesting sources. I think wouldn't mind having more of that in twitter debates. I see how this could be a time waster, but I see the benefits too and I'd say that more often than not we forget about checking sources. Also, in a debate (which is usually longer and more focused than discussions elsewhere online), both sides can use this tactic. In this case the person with better sources seems more likely to win. Again, this looks OK-ish to me.
