Depends on the section, movies section I post and then wait for liddyrules to disagree with me and/or other people attack me for hating shitty movies. 90% of the threads I post in for that section turn hostile at some point.
Games, I post and then come back to enjoy a pleasent conversation.
At my desk, TV to the left watching either shit I dl'ed or youtube videos you animals post. Monitor to the right; start on new posts, open new tabs to the posts I want to read, or have been following. I've been known to have 10+ tabs of the inane babble you people throw up onto the forums at any given time.
And as for my jokes, I rarely crack one; I have awareness of my complete lack of funny.
Start with sports, off topic, gaming, bizarro, and CE. Usually from my desktop, occasionally from the laptop. Usually have two or three Wackbag tabs open at a time. And I never worry about getting a laugh, I include a small "tss tss" somewhere in all my posts for insurance.
