Shaping "the blogosphere we want"

Paul Rosenberg's response (in part) to one of Maryscott O'Connor's recent essays about the blogroll purging...

Setting everything else aside, when Kos decides to "trim" his blogroll, and does so thinking about himself and his site, rather than the political blogosphere as a whole, he is not doing anything to consciously create the blogosphere we need--even if I had no objection to the contents of the blogroll he ended up with.

And, of course if we're not really thinking about consciously shaping the blogosphere we want, how can we possibly be up for consciously shaping the world we want?
