I think I suggested this sometime ago somewhere else within BW, but today I became frustrated/disappointed again (while looking for hosts, so it's time for me to voice my/our/the problem again:
There are simply too many profiles that are empty, useless: no photos, no information on the person, just wasting space and our attention. What's the point? The inverse of that fact is that there are too few profiles that serve any purpose. So, wouldn't the solution be to encourage or even oblige people to complete their profile if they are really serious about hosting? Does that make sense? If so, how could we/you proceed to have more and more people fill out their profiles? That is the question.
