Hopefully the fact that we're not doing this for our developer job matching site is not its death knell. We're building up developer preferences first, and then we can ask employers to create job descriptions and potentially match with developers.

Scraping, in our case, wouldn't work anyway because most job advertisements don't have the information we require.

(For the curious, my friend and I are making https://polyfill.work. Developers say what they want -- pay, schedule, etc. -- and polyfill introduces employers and developers when they want the same things)
