I don't know whether you've noticed the changes or not but my blog provider, Typepad, recently upgraded the comments section on their sites. This should come in handy to a few of my regular commenters — you no longer have to enter your information every time you comment on all Typepad-hosted blogs. All you need to do is register for a Typekey account. It's easy and it's free. Don't forget to upload your photo or an icon of your choice.
