Pros and Cons of social networking

Here are two pretty good posts on social networking:

I think Ed's post is much better in the was it displays a greater degree of familiarity with the social networking culture. Perhaps the Gospel and Culture one is better in the clear description of its theological framework.

I've read little else in the Christian blogsphere that tries to be so thorough and balanced as these two pieces. Much seems to reactionary or too 'pastoral' for my liking. This stuff is much more useful and thought provoking.
