Since Blogger/Blogspot doesn't have TrackBack support, I've just added it trough a seperate (free) service from HaloScan.com. TrackBack is a system that allows everyone reading a post in a blog to see if someone else has blogged about it. Six Apart has a good short beginners guide here.
Don't know if the new trackback link actually works tough, since no one appears to link to any of my posts. Yet at least :)
