While the U.S. Constitution clearly did not take into consideration any tweets by our founding fathers, it is probably safe to assume that Samuel Adams, Benjamin Franklin, Alexander Hamilton and Thomas Jefferson would have loved to tweet their opinions as much as they loved to write for the newspapers of their day (sometimes under anonymous pseudonyms similar to today’s twitter user names).  Those men, and countless soldiers in service to this nation, have risked their lives for our right to tweet or to post an article on Facebook; but that is not the same as arguing that those public tweets are protected.  The Constitution gives you the right to post, but as numerous people have learned, there are still consequences for your public posts.  What you give to the public belongs to the public.  What you keep to yourself belongs only to you.

human brain networks represent a balance between high efficiency of information transfer and low connection cost

Members of the audience and other Twitter users were asked to tweet during the lecture about the concepts that were being discussed, using the hashtag #csftwitterbrain. At the end of the talk Professor Bullmore displayed the resulting image showing the interconnectivity of the hashtagged tweets, and explained how Twitter networks can be compared to the human brain network. “We found that the #twitterbrain network was somewhat like the brain network in being small-world and modular with highly connected hub nodes; however the brain network was more clustered and less efficient than the twitter network. So at first sight there were some points in common and some points of difference between these two information processing networks.”

“It has been intriguing to see the spectacle of watching the twitter network grow or evolve over the course of several days. And I have learnt a lot about the power of new media to engage and communicate, and the potential scientific value of using Twitter to map and measure social networks.”

the noise is worse than ever. Indeed, it is being magnified every day as more people pile onto Twitter and Facebook and new apps yet to crest like Google Wave. The data stream is growing stronger, but so too is the danger of drowning in all that information.

the fact that Seesmic or TweetDeck or any of these apps can display 1,200 Tweets at once is not a feature, it’s a bug

if you think Twitter is noisy, wait until you see Google Wave, which doesn’t hide anything at all.  Imagine that Twhirl image below with a million dialog boxes on your screen, except you see as other people type in their messages and add new files and images to the conversation, all at once as it is happening.  It’s enough to make your brain explode.

The social-networking giant has opened its first-ever office in Asia—in the country where being all up in one another's business is practically a birthright.

Shashi Tharoor, the country's junior minister for foreign affairs, has become a major national celebrity thanks to his tweets, the candor of some of which has got him into trouble with the fustier, unwired elements of the cabinet to which he belongs. Tharoor has nearly 700,000 followers, putting him in the top 10 of the world's tweeting politicians. (He is almost certainly the only one who writes every tweet himself.)

Rebecca Whitehead, assistant director of campus visits and engagements at Winthrop University, maintains the admissions office’s Twitter account, which currently has 373 followers. She says she uses it largely to connect with other higher-education professionals, to find out about upcoming events or research.

In my own classes I've been deliberately vague about what students should tweet about. I didn’t want overly prescriptive guidelines to constrain what might be possible. Instead, I wanted our integration of Twitter to evolve organically. Given this open-ended invitation, I’ve found students tend to use Twitter for class in three ways: to post news and share resources relevant to the class; to ask questions and respond with clarifications about the readings; and to write sarcastic, irreverent comments about the readings or my teaching. The first two behaviors add to the community spirit of the class and help to sustain student interest across the days and weeks of the semester. The third behavior, when I first noticed it, was an utterly unexpected finding. (And as I've argued elsewhere, it was a good, powerful surprise that legitimated my use of Twitter in and outside of the classroom. I saw students take an oppositional stance in their writing—a welcome reprieve from the majority of student writing, which avoids taking any stance at all.)

I strongly recommend creating a permanent Twitter archive. A free service such as TwapperKeeper will track a specified hashtag, collecting the tweets 24/7, and you simply return to TwapperKeeper any time to download the archive. It's so easy to use that I've begun creating TwapperKeeper archives for any hashtag there's even the slightest chance I'll be interested in revisiting later. Another useful archiving tool is called, appropriately enough, The Archivist.
