I don't think I've ever used the ask a question feature here yet, although I do ask questions in my hub titles and then like to expand upon that and share my feelings on the subject within my hub. Questions tend to draw others' attention, so I think it's a good way to snag potential readers.
I like to reply to questions that interest me, and especially enjoy reading humorous dialog and comments that are of a sparring nature since I like to laugh. I don't care for profanity - It turns me off of an otherwise good hub in a heartbeat. Nasty just isn't funny at all to me.
Now I am wondering though, how often do you ask hub questions as well, and do you think it's an effective avenue for finding other hubbers to follow that have similar interests and views to your own.
Great question by the way! :o)
