Agreed. Having a small community and not being well-known are not advantages.
They try to say that your voice will be comparatively louder and you'll get more attention from the developers, but in a large community, you get attention from the community as well. The only thing you can get from using an unpopular project is an adrenaline rush from living on the edge.
Having a small community and not being well-known are not advantages. I am not sure I can agree with this. Smaller communities are often nicer.
