I have a number of things that I do online during the day ranging from research to listing things for sale, that sort of thing. I can assure you, I glance at the boards looking for something that catches my eye and I either drop a quick post or bounce.
I type insanely fast (faster than you can imagine) which gives the illusion I either spend way too much time posting (I don't) or that I MUST care soooo much because of a wordy post when I don't.
And I tend to leave windows open, though I try to close them. I'm lazy, what else is new.
Also I learned from Scooter how to divide a post up into interesting parts I plan to retort to and a quick highlight with the mouse and a click of the quote button literally takes a second or two to do. Long posts I make I am pretty sure I write at about the same speed most people read them.
