Windows only: Microsoft has just released Microsoft Max (beta), a combination feed reader and photo viewing/sharing application.
Let me say this: Max is slick. I like the display, and while it’s lacking a few things (I can’t figure out how to import my Bloglines subs, but that might just be me), I see that it’s got a lot of potential, plus, it IS still in beta, after all. Microsoft Max is a free download, Windows only.
(however, Max is not compatible with Windows XP Pro, just an FYI)
