Buffer recently published a full roster of all employee salaries. Do you think this is good or bad for startup founders to do? http://qz.com/160348/why-a-startup-just-published-all-of-its-employees-salaries-for-the-world-to-see/
I don't think it matters either way.
Put a number out there and it will attract some and repel others.
Some people will be comfortable working for a startup; others will be afraid of it. More than salary, that will limit who applies.
