<div class="pre" style="margin: 0; padding: 0; font-family: monospace">IYHO.... IMHO we need a healthy balance and should address the needs of all the stakeholders and participants in the ecosystem, and not blindly prioritise "mappers". Most of the energy wasted on these mailing lists and in creating things in the wiki comes from mappers - not because there is no way of modelling something, but because there are so many different ways. IMHO it would help to apply a bit more of a scientific approach to our tagging schema design to reduce the unnecessary complexity. We are modelling the world, which is a very complex entity. Making the right choices about how to reduce the real-world complexity to something manageable and yet still useful is a skill which not everyone possesses in equal measure.</div>
