Time zones, for example. A lot of remote jobs are with companies that only consider remote work to be work done from your home and only if in the same city as their office, and during the same hours. While this technically shouldn't matter, it greatly limits the success and talent pool available when you don't consider all the available time zones and cities which are great for remote workers.
Additionally, I've found working remote for companies that don't have a remote first culture to feel more like grunt in the corner that is ignored than part of a team and as an experienced professional with values and insights to contribute to the team. While that might seem like a great deal on paper — lower on costs — it works out terribly in the long run with ROI.
Working with a completely distributed team (no HQ) on the other hand is the best job I've had in 10 years, both in terms of culture, team dynamics, subject matter, salary, location, work environment, etc etc.
Posting a job is free also, unless you want it featured.
I'm glad to see more competition.
1) the typing thing you're doing continuously shifts the page when I'm scrolling through, regardless how far past I am from it. Really annoying.
2) The fonts don't seem to scale well to smaller screens (weird word wrapping)
