I also don't think that the problem is the rise of mobile devices here. My perception is that Wikipedia has developed a culture that where new people are really discouraged from starting and contributing. The problem is both social and technological. And while the MediaWiki software is open source, it forms a rather closed / restricted sub-area of open source software. They reinvent alot within their community. I'd be very happy if they did some steps like Drupal 8, integrating part of the Symfony 2 Framework. Nevertheless, Wikipedia / MediaWiki are still very powerful and I don't see any viable alternative to them as of now. It was / is a highly successful project. Not many software projects grow so old and are still relevant.
