The problem is I get a lot of replies which are (poor) jokes. Or even just people saying "I don't know". Which gets a bit wearing over time.

I think the trick is to contribute knowledgeably to a discussion. Treat it more like someone asking for advice rather than bantering in a pub (unless you know the other person well).
