I'm rather new to this site but have some experience managing similar environments. I have a degree in something from somewhere and it has very little to do with what I actually do.
Advertisers might be interested but I don't think that education is relevant to anything that MDL does. It's the sort of thing that nobody would think of asking if you hadn't told them about it. On my sites I never found that more "about me" fields contribute more than clutter. I think our posts and interactions tell other people here all that they need to know about us.
If your goal is to promote a harmonious environments then encouraging people to add things that automatically rank people like educational achievement to their profile will not do so. Let folks write it on their profile if they think that it's important or have the management post a survey.
