I'm not in the law profession, but is that (name, address, phone, etc) public information? I can imagine personal info being disconcerting.
While I've never visited Avvo's site, according to the article, there are other pieces of information there. What about the history of which cases a lawyer has won or lost? Is that public info? What about ratings and comments generated by past clients on a public website? It seemed to me the bar was miffed about that too, even though I've venture to say that's for all intents and purposes, public.
Other than your name, and perhaps where you attended law school, I'd agree that personal info shouldn't be on there. But I don't think use of public info is unfair.
I'm not sure the public rating of lawyers in the form they implemented to be the best way or even a good way of finding and evaluating lawyers. But I don't think it's bad to try or use public information to do so.
