Rather than pure web development, our early projects have included data processing, applying machine learning, and lots of dev-ops work. I think that variety of projects keeps things interesting, and in fact 39% of contractors say that they use Moonlight to work on technology different than their day jobs.
As I mentioned in a previous comment, we operate as more of a pure marketplace. If the hourly rate misaligns with a contractor's abilities, that basically means that they will not get as many projects.
Can you email me details on your version of Firefox? We're using http://Bulma.io for css - does the same thing happen on their website? (I'm philip at moonlightwork.com)
Regarding doing things manually - we've embraced it entirely. Moonlight operates off of spreadsheets and emails at this point. Our login page doesn't work, and signup is powered by Typeform + Zapier. We use Paid Labs for invoices, and Payable for paying contractors.
Because of non-scalable approach, piloting Orbit and launching it took one day (and got us new projects on the first test among existing clients). We've identified the part of an application that are most important to build, and are hoping to start rolling out pieces this month.
