I admit- I googled "jaw drop" and this dude came up- sue me!This idea converged in my brain this week after seeing so many requests from people for their Twitter PLN to speak up during a workshop they were doing on the power of Twitter/building a PLN. This was the broth and @bethstill's brilliant idea to match up her PLN with preservice Kansas State teachers was the spoon...
I would think the perfect way to show the power of the Twitter PLN would be to set up a Google Doc Spreadsheet like the example above prior to your workshop. In this spreadsheet, you would just include some simple fields (name, location, field/school setting, why Twitter is powerful). Next, make sure you let your Tweeps know when the workshop will begin. Then, when it's time, pull the trigger and ask your PLN to come in and edit the Google Doc (and Retweet for max surge effect!).
Then let your participants sit back and watch people from all over the place click on cells/edit the doc. My guess is in 10 minutes you'd see a ton of responses and several jaws open in your workshop.
So that's my idea. Too bad I don't have an opportunity to use it in the near future- here's hoping some of you out there might be able to make this happen- I promise to be first in line to help wow your participants!!!
UPDATE: Just wanted to share how this idea played out at a Twitter workshop, hosted by @tgwynn and @ewilliard . They started this spreadsheet and the Retweets started piling in. In an hour and a half they had over 60 responses! As of this writing (just 3 days later), their spreadsheet has morphed into an awesome resource with over 140 educators from all over the world pitching in: http://spreadsheets.google.com/ccc?key=0Alcvj6O0x7JjdGFlQzR6UExSN29IYkJsOExZMnRiU3c&hl=en
