But as the number of friends begins to increase—particularly over that magic Dunbar number of 150—the spell begins to wear off. At this scale, we simply can’t easily keep track of it all. When our number of connections rises above 150 everything becomes simply comments, as real conversations tax our already limited ability to interface with the network.

That mythical thing, social connection, doesn’t flow over these networks; information flows over these networks. The only reason the network ever felt meaningful was because, at small scale, the network operated like a community. But that breaks apart at large scale.

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.

Relieve yourself from the pressure of knowing all the ins and outs of every tool. Instead, empower your students by challenging them to become experts who teach one another (and you!) how to use new programs.

Group Consensus Method

Small groups of students engage in dialogue on a particular topic, then a member uses a digital tool to report on the group's consensus.

Rotating Scribe Method

Each day, one student uses technology to record the lesson for other students.

Whole Class Method

Teachers in one-computer classrooms often invite large groups of students to gather around the computer. Here are a few suggestions for making the most of these activities

When we are faced with limited resources, it is tempting to throw up our hands and say, "I just don't have what I need to do this!" However, do not underestimate your ability to make it work.
