One of the major problems for every worldwide community platform is the language barrier. Not everyone feels fit to debate complex matters in english and using a translations software to work your way through an extensive topic is a tiring thing, not to talk about the quality of the outcome which has significantly increased over the past years (at least for the most widespread languages) but still does not match what I would call close to perfect.
There are so many users in countries all over the world contributing to the database as well as to the national forums backing off from participation in these basical discussions because of this language barrier. I am sure many of them would be ready and able to deliver valuable input and it is a pity all this knowledge and expertise remains an unused treasure.
My vision of a such a community platform would be some kind of integrated translator showing the content of each and every post in the language any user has chosen as default so that everyone interested in participation could do so in the own language without any restriction. Yep, this is some kind of science fiction only - but this would finally be a real big step forward in multilingual communication.
