I don't want to hijack the intent of this submission too much, but I am really curious about a question burning on my mind. I can't help but notice the sheer number of WordPress mentions on HN and other sites lately, and while a paranoid part of me wonders if this is something of a marketing blitz, I want to try to get an unbiased opinion:

Is WordPress the way to go these days for blogging?

How does it compare to Blogger? What other reasonable options are there, and how do they compare?

Edit: And how does it compare to posterous?
