We're Mac users here in Web Communications, and as a web designer not wed to the Microsoft toolset, I've cursed Redmond's name on an almost weekly basis for the million ways they've made my job more difficult (Front Page 98, Microsoft CMS, proprietary "standards", breaking Flash embedding, grrrrrrr!)
However, I love the fact that they're
supporting OpenID. This might actually be the end of web users having to maintain 1000 accounts.
OpenID is a standard means of maintaining one user profile, password, etc. that you can then use with any participating site. Bravo!
