i would like to underline the positive aspect of social networks which was addressed in this article.
i think we are now in a phase, where applications like the channels of kyte.tv allow people to create cross-socialnetwork-networks for themselves.
what i mean is, a kyte.tv channel can be embedded in facebook and in myspace. but the real beauty is that it is accessible from where ever you are via mobiletelephone.
so i am looking forward to great possibilities, with features like these.
