Does The Internet Make People More or Less Sociable?

This introduction conveys no new idea to the reader. The first and third sentences are repetitions of a flat tautology. It's as though the thinking will come later, in the course of the writing.

But an essay of this sort cannot work that way. You need to present the reader with the result of the thinking at the outset. Then you show how you develop that idea from the materials you came by, and leave the reader at the conclusion with a route onward, in which she can take your idea into new terrain or new implications for herself.

Sherry's work is indeed the most important social psychology we have. But rather than reading Alone Together or Reclaiming Conversation, you watch a TED talk?

Illustrations aren't analysis, and TED talks aren't where one looks for substance.

The primary route to improvement here is better framing. "Is the Internet A or B" is always hopeless. Presenting a binary choice among offsetting inaccurate abstractions isn't good thinking for the reader. The question is "How is universal interconnection implemented through the current architecture affecting human sociality?" Then we avoid fatal levels reductionism at the outset, and are allowed to have thoughts more complex than binary choices.

If watching talking heads videos is your preferred mode of research, I suppose this could be considered an attempt at another approach to your question.
