Will the Flock web browser be usefull?

My guess is that this Flock will be a Flop. Right now, blogging isn't as big of a deal as everyone who blogs says it is. Yes, it is growing, but it hasn't reached the point where a huge majority of users need to update their blog right from their browser. Also, it has integration with some services like flickr, del.icio.us and others, but nobody but the early adopters are frequenting those sites. And what about users that use other sites for photo sharing or bookmarking? Flock ties you to these vendors. My guess is that Firefox and IE will incorporate similar features eventually when the time is right. The time is not right now or even soon. If all they aim for are the early adopting tech heads, then they may succeed. This will not be a mainstream browser.
