I like discussing current events and politics, particularly Canadian vs American, or Western Canadian. I am "middle-of-the-road" (the NDP is often too left for me, but I'm no Steven Harper either). I DO NOT like "America-bashing", but I am not happy with the current US Adminstration either.
As for other areas of conversation, I like to kid around as I get to know folks, and like being kidded back - for instance, I may no bones that I am a 56 year-old bald guy that has foot-long Pony Tail, and don't mind being kidded about it a bit.
I like post funny and weird pics or jokes, sharing pieces of my personal life and things I have done in my life (though there isn't much that's all that exciting), and so on.
I don't like getting into intense Flaming sessions, I'm a generally pretty nice guy, if I do say so.
