The thing about all these is that they’re not a shared experience—they are my experiences, which I am sharing with you, but you probably cannot experience with me—my thoughts or fascination with the article I just posted, the feeling of getting on that plane, or the thrill of watching the Sharks tie the game. Perhaps you can compare your notes of your own experience of these things; that’s what most Twitter conversation seems to be, to me, but the experiences are not shared.
This differs from a discussion in a community, such as the type that occurs on SB Nation game day threads. The conversation does not center around any one individual’s experience, but rather the collective condition of the community. The conversation is the experience. Each comment is driven with the purpose of evoking and expressing the emotions that the community experiences, and particularly the ones they hold in common.
