I think some of the 23 Things will be of use in the workplace eg. iGoogle, wikis and RSS to name a few. I was delighted to see a decent looking blog I'd created on the library website, so roll on the next Thing!
iGoogle was great and very useful, allowing me to log in onto the same news items/widgets etc. both here and at home.
The rest of the family are hoping to learn some of the gizmos since they're falling behind with the technology too.
