A few rules:
1) Breaking the fourth wall (meaning making comics about your own comics) can only be funny if you don't do it in EVERY DAMNED COMIC. Take a break and find a new joke every once in a while!
2) 1337 speak or whatever isn't funny. It's dumb. Drop it.
3) Don't apologize for your comic mistakes in subsequent comics. It doesn't fix the problem, and it simply creates another comic that isn't funny. Your best bet is to donate money and get the privlidge to edit your comics.
4) Don't make comics about shit that happens in the forums. That's what forum posts are for, and the reason they allow you to insert your own text. AND they're not funny.
If you can swallow all that criticism and follow those four easy steps, it's not impossible that you might become a good stripper. Give it a shot.
