I just found that a new browser called Flock is just launched. I just installed it a couple minutes ago, so I cannot say much about it. It seems to be a great "social" browser, though. Flock allows you to post to your blog directly from its browser by clicking 'add to blog' button. It also has some other cool features as described here.
I'll just give Flock a try and we'll see whether I'll make it my default browser or not.
p.s. this entry is posted using Flock's "add to blog".
