Jennifer has posted about it on her own blog, you can view here - Spockon.me - Shorten Links by Spockholm.
Since the 3rd party link shortening services are getting slower due to overloading and links that Link-A-Nator generated, Spockholm has decided to create his own link shortening service.
You are only able to get a shortened link from Spockon.me through the Mission Crew Link bookmarklet, so most likely it'll be integrated into the Link-A-Nator bookmarklet too!
For usage tutorial of the bookmarklet, please click on the link above! =)
