Oh i see....
Well i'm no expert, i'm basically new at webpage design but i would suggest more videos for guests.
If you look at the poll on you site, the majority of people go looking for videos. If you get more hits, that means more people visiting. Some of those visitors will stick around and post.
More visitor = more potential posts
Are aikidoka secretive card players? Maybe it beacause most of us, like you, do our talking on the mats
I have only 1 tiny video on our site, but hope to get more soon. We're a small but growing dojo. We do have pictures though.
Keep up the page, its nice.
