Bill Ferriter addresses the eternal question - well, it has come up occasionally around here, anyway - of whether it's snobbish or arrogant not to follow everyone who's following you on Twitter. For his part, he chooses to follow only a select number of people, and thinks that's perfectly in keeping with the function of the tool (especially for educators):
After all, I'm trying to learn from the people that I'm following, and that's hard to do when good ideas are buried under piles and piles of messages. My decision to follow a small handful of people--instead of everyone who follows me--is about information management, not arrogance.
And in my opinion, managing the tidal wave of information at their fingertips is probably THE most important skill for 21st Century learners---whether they be adults or kids---to master. Just because I can follow a thousand people doesn't mean I should!
