spoiler: rockmelt could have just been a plugin, but who invests in plugins? they're not entering the browser war, they're entering the attention war. aiming for acquisition by someone wanting to look at facebook data? (or fb themselves, to block, or for that same reason?) (unsure of the etiquette on posting your own articles, do to tell me off if i'm doing it wrong.)
