In my experience https://www.levels.fyi provides much better information than random tweets. Not everyone works for a FAANG, but it's useful to know what their influence is in the market.
I wish there were just a little better filtering/sorting on their data. I want to know what people with my years of experience, in my metro area, in my specialization are making. You can kind of get some of that info, in certain forms. If their data (the data that is already publicly viewable on their website) were in a relational database I could write a query in about 60 seconds to pluck out what I want to know.
So to expand on the shortcomings: I can filter by metro area and years of experience. But the result is just the table of data points. The only sortable column is total compensation. There is no aggregate data.
What I really want to see is the histogram chart from the link below, but with the filtering results applied to it. It seems like the only thing you can do with the histogram they give you is select metro location.
They could set a minimum number of people in the results to be > $THRESHOLD or you'd get "not enough data". I believe Facebook ended up doing something similar after a college student targeted his room mate with a number of overly-specific FB ads, wrote about it, and the story went viral (before 2016 elections)
