The ideal blogger shouldn't have an audience 100% enamored with their writing. A writer isn't doing his or her job right if they have everyone on their side.
An effective blogger is someone who creates dissenters because they bring something new and unique to the table. They take what makes news and synthesize it in a stimulating fashion. The goal isn't to get all readers to agree—although that is undeniably nice—but to get readers to care and incite reasonable discourse.
And of course, this person should have equal parts knowledge of their subject and the cajones to substantiate their claims.
I believe I am this person. I write with snark and wit, and have been doing so since 8th grade. Seriously. My English teacher found a Weekend Update-type sketch I wrote for my friends the floor of her classroom; it spared no prisoners and mocked teachers and students alike. She confronted me about it, telling me it was so filthy and appalling that she couldn't even give it back to me to throw out, that she had to keep it.
But it was sure as hell funny, and Mrs. Lavine be damned, this was my calling. I've since (partially) honed my writing skills since I was 13 and the present day version of myself is ready to impart his controversial, funny, unique thoughts unto the world.
Hopefully you will read, but it's OK if you don't. I understand. There's a 1-in-7 chance it's a Saturday. Maybe you want to spend some time with the kids.
