Harold, The power of the network is so difficult to help others understand who don't LIVE it. What a simple, but powerful example. What you describe seems so simple: I post a (desperation) question to Twitter. You see it and are kind enough to share something. That 'something' turned out to be - well - perfect for my writing at the moment... and (I am looking forward to this part) work we are planning for the future on studying learning enviornments. So true that: This stuff won't happen if you (and sooooooo many others like you) don't share. I leave this comment noting that I do a POOR job of sharing...and with new resolve to do better! Thank you again!
