If we are going to develop a community website for non geeks, is it ok if we implement openid registration. How much openid is acceptable in non geek community. Anybody having any idea about this.
Do both - provide OpenID for those that want to use it and have a regular user account signup for those that don't. You could even go all the way and become an OpenID provider and allow users with regular accounts on your system to use them as OpenIDs on other systems.
In short, OpenID is OK as long as it's not the only option.
One small note: If you do decide to provide OpenID authentication, you need to be prepared for users locking themselves out of their accounts. You should also provide a mechanism for changing the associated OpenID.
