It would be great if you required companies to post pay ranges. Some jobs that I may not find interesting might become interesting if the pay is right. Without pay, it's very hard to determine which are worth pursuing.
I agree. That has been a core policy / goal of http://WheresTheRemote.com/ (although the site has not really gotten off the ground yet). As a professional I don't want to waste my time reading and replying to ads that aren't worth my while, that don't offer appropriate compensation for example, so I want to know what the advertiser is willing to pay. One of the principles of WheresTheRemote.com has been to require advertisers to provide a rate or range and pay a fee based on the highest advertised rate, to encourage accuracy. In my experience, requiring advertisers to include rate information is not a common feature of job sites.
