The real problem is that Wikipedia has arbitrary rules about what is relevant and what is not, and unfortuntately the gatekeeping process has become very centralised. I put up an post on MaidSafe which lasted about a week before being taken down for being too similar to a previous failed attempt, even though it was totally different. I complained of course but got nowhere. Same happened with the followup, although that was rejected for different reasons.
By the way @drirmbda is working on a wiki which might go some way towards what you’re suggesting.
