I don't really have any recommendations for changing the format of this program other than finding a way to get people to do more commenting on each others' blogs. I've tried to go through the spreadsheet and find people who might need encouragement because my facilitator has been a wonderful "cheerleader" and those comments kept me going. I found myself checking several times a day to see if anyone left me a message! I would love to have known who "adopted" me so I could've made sure I was also following their blog.
I'd have to say my favorite learning exercises have been the more creative ones involving image generators, spell with flickr, Slide.com, etc. Creative Commons is going to be VERY useful and I hope I really do use VoiceThread. I would definitely participate in another discovery program, especially if it was offered in the summer. I tried this once before during the school year and I just couldn't keep up. Thanks for teaching me so much this summer!
