"Intervention Share Fair"...couldn't we use a wiki for this?

This year, the school where I am placed has decided to adopt an "Intervention" program, for students struggling in math and those struggling in reading.  Every classroom has a new math "Intervention" block twice per week, and teachers also incorporate reading "Intervention" during the regular Language Arts block.  Grade level teams have planned how they will use this time.  Today, we had an "Intervention Share Fair" after school, to open up conversations between grade levels regarding what is working, and not working, with grade-level "Intervention" models .  I think it is really important to have this vertical communication between grade levels and build off teams' ideas.  However, I started thinking that having a school-wide wiki, specifically devoted to "Intervention" strategies, might be a better way to have these same conversations.  Because the meeting today was afterschool, and an hour and a half long, I felt that many teachers were not fully invested in the sharing, simply because they were stressed and thinking about everything else they had to do.  Also, many grade level teams are using almost identical models for this new block.  By putting all of this information on a school-wide wiki, teachers could visit it - to add new strategies and learn from their peers - on their own schedule and when they have a need to share.  Also, they could quickly figure out how grade-level models are similar or different.  I think this could be a very meaningful use of a wiki as well as teachers' precious time and energy :)
