For the good of the cause, choose one or two of your Tweeps, whom you consider to share very relevant, challenging, or useful information on a regular basis. Compose a quick tweet on Friday (that's tomorrow already) like this:
#techitu #ff @jgates513 @willrich45 Great consistent tweets on #edtechLet us know briefly why you follow them. Do they post on your subject? Do they share great Edtech resources? Do they challenge you and sharpen your practice?
Those of us trying to build our own PLN via Twitter can watch these #ff posts and choose, hopefully, to follow those who are most relevant to us.
Good luck and great tweeting.
