I agree–entirely–about good quality blogging establishing someone as the “expert.” Even mediocre blogging helps to establish a web presence.

I’m not going to pretend that I understand how the Google Ghosts evaluate the “importance” of websites, but blogging does seem to be highly respected by Google.

I don’t know how important it is to the much less used Yahoo and Bing.

I think the toughest part is selecting a niche and having your blog stick to that specific niche. It makes sense that you’d want to litter your entries with targeted keyword phrases.

Of course, selecting the keywords phrases can be quite a bear.
