There are many great US financial blogs, there are even probably over 1000 by now. People always mention GRS and SimpleDollar because those were two of the earliest, but that's really ignoring many other excellent blogs that have come into being since. GRS and SD often post about non-financial topics too, like baking bread.
One I would recommend is Moolanomy (www.moolanomy.com
). I also really like Generation X Finance (www.genxfinance.com
). It's also about the topics they tend to write on and the personalities of the bloggers. I don't get as interested in frugality topics by nature (though I am more lately). There are probably more "frugality" blogs in the US than pure investing blogs. I was just talking to FourPillars about this. I think it's just the nature of the investing environments in the US vs. Canada.
