Blogging, I mean. Up till now, I had known exactly one instance of a successful high-volume blogger who just walked away from it: Russell Beattie, who closed up shop in April 2006. Well, he’s back. Two things you need to know about him: he is extremely expert on the mobile technology business, and his surname rhymes with “she catty” or “he ratty” or “me fatty”. I’ve subscribed.
