Well as long as you aren't expecting to get a great rush of new people joining the dojo. As I said before I have done a lot of demos both at anime cons and not. We have picked up a few people from seeing a demo at a con or elsewhere but mostly it's just to kind of spread the word and to let people know what kendo is really like as opposed to what they imagine it's like (as some have said earlier). If you do a demo try to get the crowd involved a bit. Usually I have a part at the end where we let people in the audience come up and whack us a couple of men strikes to let them know what it's like. When you get the crowd involved you'll be received well usually. Also, make sure you are careful when you get the crowd involved... last demo we did one of the iai people was letting people hold his iaito and someone accidently cut their thumb a bit ( after having been told that it would cut.. some people don't listen so it's probably better to avoid it all together)
