One of the best resources I have found when it comes to discussions on inflation, the Fed, and the economy in general is a website called wolfstreet.com: Wolf Street | The stories behind business, finance, and money

The author is fairly prolific usually posting at least one article a day. Occasionally there will be two or three articles a day. Furthermore, the comment section of his articles are very active (including the author). His articles are very well sourced (usually from the Fed or other such reliable datasets). The author is very knowledgeable and very data driven. In the year or so that I have been reading the site, I have learned a lot about the ins and out of inflation (such as what is driving inflation). It is a masterclass in understanding the Fed and inflation. I cannot recommend it enough.

That said, it is not a good information source for stock investing. it is more for fixed income securities. Don't get me wrong, the author is a very smart person and he picks up stock stuff fairly quickly, but it isn't his primary cup of tea. The comment section has more than its share of cranks, goldbugs, and nuts, but there are also many other knowledgeable commentors. The author usually does a good job refuting the nuttiness.
