How I use 80000 hours
I am not looking for a career, but I use this site to understand what the most pressing problems in the world are. Under the resources menu they have a list of (what they consider) the top global problems and links to information on what the problem is, the scale of the problem, the extent to which it is being worked on (neglectedness) and how easy it is to solve (solvability).
I find this a very useful quick guide to global issues as well as how they might be tackled. I use the information in my fiction as well as in articles I write on ideas to improve the world.

Why I use 80000 hours
The information on the web site is free and well referenced so that I can go deeper into any of the issues if I want to. It's well curated, making it easy to find relevant information. Also, i'm interested in what might make the world a better place.

Why I trust 80000 hours
As far as I can tell, the research conducted is good and impartial. All claims are referenced.
80000 hours is a London-based non-profit organisation, funded by donations. The approach is based on effective altruism, a philosophy and social movement that advocates making rational and impartial decisions about where to focus effort to resolve the world's problems. It's not something I subscribe to wholeheartedly, since I think rationality has limits, but I think the intentions are good.
My reservations about 80000 hours
I'm not sure I agree with their criteria for selecting issues. They focus on scope, neglectedness and solvability to identify which issues, if tackled, could have the greatest benefit. These criteria surface some ideas that seem quite unlikely to me and even verge on fear-mongering, like defending ourselves from individuals who might want to engineer deadly viruses.
There is also the possibility that naming these as the 'top problems' undervalues many of the other really important problems that people around the world face. This is an elitist project, run by elites, for people who have lots of choices. For the majority of people who don't have the same luxury of choice, everyone can make an impact for the better on problems that may appear just as big in their own contexts.
Conclusion
Were I younger and starting out on my career, I would certainly use this site as one input into my decision-making. Aside from career choices, it contains some useful contributions to the complex choices we face as a species and how to allocate resources to solve them. Their ongoing research into current challenges is illuminating.
