I’m thinking this might be less the interface and more the lack of translation – German, Dutch, and French isn’t a particlarly large slice of the population. Maybe we see an uptick if some of our Chinese-speaking users help translate the site and Picard, and then (gently) promote it on other Chinese messageboards. Switching fully over to the aliases might also help, but it’s probably not as much of a hurdle as nearly all the documentation and discussion being in English as well.
My concern is that we simply don’t make MB less powerful as we make it easier to edit. Advanced users are already used to working on several pages to get all the data we want added (or using scripts if they actually have a browser that supports them) so that won’t be as much an issue, but as slick an interface as BookBrainz has, it always felt like I could only could only touch the surface rather than really digging in like I do on MB – and I acknowledge that’s likely not reflecting its actual capabilities and is more just my perception. I know web design now involves some degree of flashiness, but I feel we should be able to find a common ground that is sufficiently polished to not give the new generation the impresssion of being outdated while still allowing editors and scriptwriters the ability to actually work on the data.
