Ever wondered what Hashtags are on Twitter? They’re words with #’s in front of them. Today Sherice Jacob (follow her at @sherice) from iElectrify explains what hashtags are and how to use them. Twitter is a great place to find and follow people with the same hobbies and interests as you have. Unfortunately, once you have as many followers as Darren does, it starts to get overwhelming to stay in touch with them all, and make sure the right information goes to the right people.

one of the functions that networks such as Twitter does is to serve as something of a human powered feed, a real time living stream of links, content and conversation often times generated by our friends, peers or the people we look to as "filters"—indivisuals who we trust to seperate the wheat from chaff.

the internet is still about information—but it's also about attention

We have a deficit in attention.

Luckily for Twitterers, there’s Mr. Tweet, a free recommendation service that analyzes your current network to suggest new friends and members whose feeds may be of interest. Like the Shorty Awards and many other third-party applications that make use of Twitter’s platform, the company has no official ties to San Francisco-based Twitter, which allows people to post messages up to 140 characters in

If, like myself, the math makes you wail and gnash your teeth, try the following. Evaluate your network, divide it into groups, give each group a number and determine how many people you have representing each group. Then follow this link to a Shannon Index calculator, enter your the number of people you have in each group, compute and read the value for H1.

I think where I’m going with this is that I worry that the ed. tech. blogosphere is reasonably saturated.  Related to Darren Draper’s post on Twitter Set Theory, I feel like there are some central figures whose spheres overlap considerably and a whole lot of us outsiders trying to penetrate that inner circle.  It’s as if folks like Will Richardson, David Warlick, Wes Fryer, Vicki Davis, Dean Shareski, Stephen Downes, Chris Lehmann…(and, yes, you Scott) are having an awesome cocktail party conversation and I’m standing on the outside staring over their shoulders and listening in, trying to get a word in, but not penetrating that conversation at all.  I know there are LOTS of us on the outside looking in. 

My theory is– don’t worry about getting your voice out there, or comments, or rankings, or even being invited to the right parties (inner circle) — rather focus intently on children, your vision, and leaving education better than you found it. Concentrate on helping those within your sphere of influence to make principled changes in education that is in the best interest of kids.

g Stone Phone is proud to announce the release of three brand new applications for the iPhone. All three applications make use of the iPhone’s built in camera, but with differing intentions – one app, TalkingPics, has many practical applications, while another, called iGraffiti, is just pure fun. The third application, Twittelator, is a full-featured Twitter client for the iPhone with the ability to send a map of the user's location with one click and automatically upload snapshots to TwitPics.com.
