Accroding to the survay by internet.com and marsh research which was conducted over 300 internet user (50% male, 50% female, 20% each of 20s, 30s, 40s, 50s, 60s), 263 of them were using sites that requires authentication. Among them, 28% of them knew about OpenID, and 15% were using OpenID.

Since the number of sample is pretty small, and the distribution is not equal to the demographic pattern, there apparently is much more error than some other survay. Even then, it is an encouraging number.

Remember: a similar survay back in February where only 12% knew about OpenID and only 1.2% of them were using it. Awareness is 250% and usage is 12 fold!

We are close to the take off, I guess.

I wonder if there are similar statistics for U.S. and E.U…

If you know the figure, please let me know!
