That's a good point. The wider issue is of course that some people are smart, but not good at writing, and they might be sidelined in an organisation that leans heavily on writing. However, the corollary of that is smart people who are not good at talking get sidelined in an organisation that does a lot of talking. So that's an issue you will always have: the form of communication you focus on will always put some people at a disadvantage. It just means you have to be aware of that, and try and keep an eye open for people who have important things to say, but are struggling to get them across.
