But then, isn't it better to have one high-level overview instead of 3 overlapping overviews? (3 overviews do not make it easier to get a quick grasp of the project.)

I don't have a quick solution - it's much matter of taste (and balance).

BTW:

- Any plans to add some external measures of interest? (E.g. GitHub stars, arXiv trackbacks, SciRate scites/# of comments?)
