Want a little more technical info on the new Safari Beta? Here's http://daringfireball.net/2009/03/safari_4_public_beta a commentary about one person's likes and dislikes about it. De Prez Jim Hamm comments that it was an interesting read.
Anyone else using the new Safari Beta? How's it going? Personally, I like the Top Sites, and have set up a dozen of my most-frequently visited sites. When something new has been posted it is indicated by a star. You can rearrange the Top Sites. Anyhow, it looks snazzy.
