> By requiring users to share their wage information at signup

This seems like a bad idea. Aren't you concerned this will lower the quality and accuracy of submissions? I know when some website forces me to put in details I don't think it needs I put in garbage.

Also you're asking people to submit data when they have no idea what data you already have. Are they first to submit?

This reminds me of Auto generated pages with no content or no answer yet that's not clear from a Google SERP. You get the "helpful" message like "be the first to post X". I actually wish Google would downrank questions with no answers and empty wiki pages.

It smacks of clickbait is what I'm getting at. If you measure it you'll probably find your bounce rate is really high.
