Warning: geekiness ahead.
I’ve been using OpenID (via MyOpenID) for a while now, but I just found a sweet little app that makes it even better. Yadis is a WordPress plugin that allows you to use your own WP blog domain as your OpenID URL. So, http://brendonconnelly.com is now my URL, rather than http://brendon.connelly.openid.com. I like it.
Alternatively, if you don’t use WP but do use MyOpenID, you can configure your account to use a custom domain. This’ll get you something like: http://openid.brendonconnelly.com. Also good, but still not quite as cool as the straight URL that Yadis provides.
If you don’t have an OpenID yet, go get one. You’ll want it eventually, because who wants to remember all those passwords? Here’s a list of OpenID providers.
