I know that one thing I don't like about https://weworkremotely.com is that many of the listed jobs are not truly remote (they are limited to one country). At least on this board I can filter those out.
I think the term "transnational" would fit what you are describing better than the term "truly remote." The US is a very large place. Someone working for an SF startup from their Florida home is just as "truly remote" as someone working from Mexico, Canada, etc.
One of the key differentiators is the ability to see which jobs are truly remote (like nomadlist does) vs. remote within a particular region. The other is that this job board is focussed solely on coders (whereas weworkremotely also caters for designers, business admin, etc). Hence the optional Github authentication.
