Well one of the most important things of becoming successful with a blog is to enjoy what you do.
Probably one of the worst things about blogs is when you first start you think nobody is actually reading but after time you'll start getting regulars making comments and linking to you.
Its a GREAT blog that you have there! Keep it up, why not? Unless you hate posting... i mean, if you like what you are doing why not? if you are having a blogger burnout, take a break, don't be rash and take down the blog!
I have to agree, I think it's a great blog, I wouldn't give it up.
Are those T-Shirt designs for sale? I love a good "Screw you this is how I feel" shirt.
If your starting to feel burn-out try changing up your theme. I've actually went through a handful of different theme's through the life of my blog, just to rekindle that thrill of posting.
