This is a very short post!
The poet I could most readily see (or wish to see) as a blogger is probably Emily Dickinson.
She was reclusive but corresponded with her friends via letters. I think this would translate very well to blogging! If she were a blogger, your blog roll would be filled with poems. You would also have essays about her favorite books and she would probably take frequent pictures of her garden, possibly accompanied with still more poetry. (According to this article she liked gardening.)
Her posts would of course be extremely awesome.
Now that I think of it, what I think would be pretty amazing would be if someone did a Dickinson version of Pepys Diary.
