Comments with OpenID

I just tweaked the settings on all three my blogs to disallow anonymous comments but to allow OpenID.

• What is OpenID good for? It means you can use your LiveJournal login (or that of any other site that supports OpenID). You won't need to use a Google account if you don't have one.
• Isn't it insecure to share passwords? Yes, but you're not sharing a password. Google simply gets told whether or not the other website validated your account.
• How does it work? Click a comment page on this journal as normal. Then choose OpenID, enter your journal's URL (example: http://example.livejournal.com), and you'll be taken to LiveJournal and asked whether or not you want to validate your identity. Click yes and your comment will appear, complete with a free link back to your blog. Again, the only thing LJ tells Google is whether you clicked yes or no; no private information gets shared.
  
• But what if I don't want to use this? Then don't. You can still comment with your Google account. I just figured I'd give everyone another way of signing posts.
