FLOCK! Its a new browser based on the gecko engine (Mozilla, Firefox, Camino et al) and it includes some pretty neat features, and almost none that you are used to.
I’m typing this in the builtin blog tool. You can set up your blog really easily, and once your entry window is open, you can axctually drag stuff straight into a little box, to blog it. The tool also retrieves your previous post titles. There’s also a builtin flickr client, and the bookmarks manager is like nothing I have ever seen.
You no longer need to submit your name to a list and wait to be invited to join. I got my dev copy this past week on invitation and have been enjoying the exploration, but I note now that the latest version is available for all to download.
Versions available for Windows, MacOSX and Linux.
