that's a good point. it is also true that us geeks tend to be too into technology, rather than understanding the people and situation actually using the solution.

i don't use twitter or SMS, and i use my cell phone simply for free calling with my folks, so i don't assume that twitter apps (or cell phone apps) could help students or school administrators.

knowlege about the market is always a far more significant unknown for me than technological unknowns.
