You could edit Special:Community to ask users to fill out more of those. Perhaps create a maintenance template/category that you can add to articles where the history and synopses sections of articles haven't been filled out enough. This template might be similar to the Stub template.

Another alternative (and maybe more far reaching) is to make an Announcement asking users to focus their efforts on this sections you're referring to. In the Announcement post, I'd link to a forum/Discussions thread you create going into more detail about what you want. :)
