I've read everything on WP that currently exists about OpenID. I understand the broad concept, sort of, but, being a non-techie, not the details. Can someone (very non-techish way) explain:
1. If a person's Blog "A" was about horses and Blog "B" was about peanut butter and they chose Blog "A" as their OpenID, to comment, say on a FOOD website: would the comment with 'horse' ID make the writer look dumb/irrelevant/inappropriate?
2. Using same examples, say Blog "A" was the OpenID listed on many sites and, for whatever reason--by choice or involuntarily or by hacking, etc.--Blog was de-listed/deleted. Would blogger have to 'start over' at sites --loose identity, be locked out and have to re-establish/convince who they were/are with Blog "B" --say on bulletin boards, forums, etc?
3. If using Blog "A" as OpenID: after signing in/registering to a website, does that mean everyone can see the address of one's blog? Or can the blog's address be made private/hidden?
3. a. I'm asking about privacy/hidden address because: supposing a comment triggers an unstable person to start stalking, doing unacceptable things; how could that even begin to be stopped, once someone had the address of one's blog?
b. Is OpenID Okay --re: spam, because WP would block the spam if spammers used the
blogger's OpenID address to get to the blog?
4. What are any disadvantages to using OpenID?
I understand the advantage given for OpenID, no more new names-passwords on websites, and techies must have a good reason for inventing this, but it sounds macho/techie/new toy-ish and I need more understanding. Thanks for your in-put.
