And so; websites with many writers should add author rel attribute.

Interesting, how Google is using Google+ as an identity provider. Well, you won't be able to find "all posts by wisty", since that's not my real name.

If you don't want to be found, no. If you do, adding a nickname to your profile on Google+ will (either now or eventually) allow them to make that connection.

love it John, great script too -- looks like your hard work learning JS all day paid off ;)

What tool is used providing the link info in the search results?

What do you mean? It's Javascript to pull in the person's name and ID, off of which we construct the URL to get to the "author search". Do you mean something else?
