I don’t know her, but I am happy to see Caterina Fake is blogging again. She writes intelligent, interesting posts, particularly if you are a practitioner of the web arts.
I stumbled upon her blog in late 2004, when I developed a mild obsession with flickr (and last.fm), and I promptly added her blog to my feed reader. Seems like she stopped posting a while back, maybe shortly after Flickr was bought by Yahoo! Start by reading her post today (and the related post from 2003).
