I like to read hubs which show me some of the writers personality.
By this they show enthusiasm for their subject, they can do this in many ways with a intended pun which theypoint to as a joke, crafting emotional language and sharing good information.
I don't always like overly aggressive writers, they often lose the argument for me precisely because they are too emotional. Also using hubpages as a psychiatrists couch can be a turn off for me.
A word of caution about writing humor, be very careful. I have written a couple of hubs which to me were meant to be humerous. Though self deprcating, some readers thought them very serious and it can make people feel awkward about coming back if they find that what they thought was serious was really a joke against yourself as a writer. Humor is very subjective so be very cautious. Make sure you know your audience.
