I feel similar, and while I don’t have 1200 posts (and I’m also not nearly as funny as you are) I want to do something that actually really challenges the way people think, versus just making that laugh about something. To me, the greatest comedians are people like George Carlin, Sarah Silverman, Bill Maher, Richard Pryor etc… because they force us to address ourselves and our society, rather than simply finding a witty mix of words that causes laughter.
Perhaps try writing about a political topic you are fired up over? And don’t try to change your tone. I never saw any of your non-humor work (other than one table one world I think), I’d be curious to see it.
Ultimately, you are a talented writer and so if you focus on who you are you’re bound to be successful. I think.
