Mike Pinkerton is thinking about what to do with Chimera. He asks "Who aspires to be number two in an already over-commoditized space?" I for one hope he doesn't stop work on it. I still like it a bit more than Safari (and not just for the tabs). I see this as being like iChat and Proteus. iChat is nice because it gives the person who just bought their new mac a way to do IM. They don't have to think too much about things, it does all the basics, but it is missing key features that anyone who has used IM for a while misses (lack of groups for instance). Proteus has all that and more. It fills that space beyond the basics. That's where Chimera fits in my view (and I'd miss that cool bookmarks panel that slides out from the side. I personally like that better than Safari's bookmark stuff.
