It is an issue of humble-ness for me as well. I'd rather be queried for data then have the thought/feeling I am forcing it on someone who doesn't want it.
I think this, and other things read here on HN have got me to accept the fact I need to follow suite.
Am I correct in saying that another potential benefit of this is that keeping the status of a project public makes it more difficult for the creator to ignore/procrastinate/quit the project?
