Yes, currently it’s only a link. That’s why I said that we maybe could do something with that.
Having a separate, non-link reference would be better in my opinion too, I’d fully back you there. Not sure if Contribution Story is more important than Bio though. Shouldn’t the Bio on mozillians.org say anyway what awesome things you have done for Mozilla anyway instead of some generic “In my job I work as …” sentences?
For example the following criteria (just some suggestions of questions one might ask themselves):
Bio: Projects you work on, the project you spend most time with, your favorite product, … (so everybody coming to your profile knows what you’re working on)
Contribution story: how did you get involved with Mozilla? why exactly did you choose to contribute? what was your first contribution? why do you contribute? why should others contribute?
I think there should be a second field in the “Bio” section for the contribution story. Maybe we should file a bug for that. Would you like to do that since it was your idea? If not, I’m happy to do it.
