@ deeplyrootedsolidlyplanted - whatever you write is going to be in your own voice, so don't worry about whether or not it's been done before. As for getting traffic, a few days of existence for a new blog isn't long enough to get any traffic really. It takes time. I've got a lot of subscribers but have been blogging here for just over two years (and have been blogging - but not on WordPress) since 2003) and it took a good few months for me to get much traffic at all to my blog.
The most important thing is to make connections with other bloggers, which means finding other blogs to read and to comment in, and to make connections with whoever comments in your own blog: reply to comments, it's important even if you don't think it is.
Also Timethief who is a brilliant blogger here on WordPress has some great posts in her own blog One Cool Site and here in the forums that will help you. Here's a recent thread that's got info in it from her that should help you: http://en.forums.wordpress.com/topic/how-can-i-encourage-comments-and-discussion-on-my-blog?replies=16
