Agreed, Anthony. I think that some sort of Facebook and Twitter integration would put them right over the top, but I understand how that would be difficult as it would cause more relationship problems and would make it harder for Google to carve out their own social niche, which is obviously their intent. I’m sure that, once it is all public and API’ed and whatnot, that those integrations will quickly follow, however. It’s already pretty cool what people have done with Chrome Extensions.
