I already used OW on my smartphone and it was working very well. From my experience I know that many mobile versions of websites are worse than original ones. So I would advise not to change anything or prepare for this carefully and precisely because it will be very easy to srew up something in site which has got so many options of using and it will be hard to retrieve someones good opinion about it.
OpiWiki is designed to work well on desktop (mouse) devices. Would you like to see a mobile version of the site?
The site already works very well on mobile, but having an app (maybe not now, but in the future) could be huge. The idea of the site is very mobile centric-it lends itself to small time commitments when one has a few minutes to spare. I can easily imagine OpiWiki becoming a default app that one goes to to entertain oneself by voting and giving opinions.
Already added a couple of written opinions from my cellphone before, and they went off without a hitch.
However, the use of an app is not for fixing browser bugs, but rather to sell features and to spread the word (and to make $'s too, obviously).
My suggestion is, finish the page, then start writing different, not-very-important things you'd want to do with an OpiWiki app. As they grow bigger, delete the redundant ones, or pull apart the ones that are too hard to do, or too important (because of many counter-intuitive reasons, the most common-sense-y of them being that, if it's so important, why do you want to make it app only?) and once (if?) you have around 20, give the app serious thought. Hire people, make money through the app to pay them, etc.
For me it doesn't really matter. I think it may be beneficial for the site though. I guess I'd focus more on improving the main version rather than on the mobile version.
A mobile version of the website, no, I wouldn't like to see that. It work perfectly from a mobile browser as it is.Instead in the future possibly an app to allow for quick easy access based of Alien Blue (for Reddit). Many people will see the app icon or a notification and just quickly check what it is, maybe contribute a little more than usual. Compared to having to load up the page and actually putting in effort (shock horror).
