I’ve updated my DasBlog to version 2.2.8252.15582 and it has OpenID support! If you have an OpenID you can now use that for posting comments to my blog. I’m not taking the same stand as Aaron Hockley though, refusing to comment on blogs without OpenID support (at least not yet…).
So why use OpenID except from identifying yourself on my blog? :-) The number one reason as I see it is that you have one ID to identify yourself across multiple web sites. This will remove the need for "forgot your password?" links, your favorite pet etc. Also that you rely on one provider for your id that you trust (hopefully) and don’t have to "give away" passwords, which you probably only have a few of, using them on all the different accounts you’re creating around the Internet.
When you sign into a site using OpenID you get redirected to your provider for authentication. Here you can choose how much information you want to submit about yourself to the site you’re logging on to. E.g. you may chose to send no information at all, just your name or email etc.
If you want to know more about OpenID and how it works, check out openid.net. Scott Hanselman has a Weekly Source Code edition of OpenID and also a podcast.
Don’t have OpenID? I use myOpenId.com where I’ve also added my domain (torresdal.net), allowing me to use that instead of [myname].myopenid.com. My id is jon.torresdal.net. Another popular way of using your ID is to map it to your web site. Below is an example from my web site using myopenid.com:
<link rel="openid.server" href="http://www.myopenid.com/server" />
<link rel="openid.delegate" href="http://torresdal.myopenid.com/" />
<link rel="openid2.local_id" href="http://torresdal.myopenid.com" />
<link rel="openid2.provider" href="http://www.myopenid.com/server" />
This way I can use blog.torresdal.net as my id. However, one side effect of this is that many blog engines use the name before the dot as your name. If I use my blog url as identifier on e.g. a blog hosted by blogger.com, the comment will say "blog said…", which is not very helpful.
I mentioned myopenid.com, but there are several other suppliers out there. Just Google openid and you’ll find many.
PS! All comments to this blog post is expected to use OpenId! :-)
