why do we still use chalk?
- it is messy
- it is difficult to write with
- it is difficult to clean off the board
- it necessitates black boards, which make that horrid screeching noise
- chalkdust

i guess its cheap. but that noise. its so annoying.
i just talked to a real class for the first time today at my university. i talked for about an hour-the whole time holding chalk. my black pants are now all chalky.
i cant help but think how much better my pants would look if we used white boards and erasable markers(like a focus group determining the color of your next toaster) instead of black board and chalk.
