This is a very informative post. I looked through the intire text and did not find a refference to the word "sticky" as used in the above comments. Can someone out there help a new guy like myself understand "sticky" ? I think it means that this text should become an additional and intigral part of the institution. i.e. rollitup.org community learning center. I wonder if it is possible to find visual examples of some of the terms above.
