I think the lot of us have just found our own happy place. We've streamlined our finances, keep an eye on our own efficiencies, but have found a new equilibrium point that works for us. There might be a couple face punches we could take, but maybe we don't want to go there yet.
That, and MMM has already tread upon a lot of areas, so there's less that's interesting today compared to previous articles such as Shockingly simple math, which got me to buy ERE's book, and was a real eye opener. The house renovation articles I look forward to, but wireless? I switched to Virgin Mobile from Verizon, sure I could go one better(Ting/Boost/Republic), but that's scraping at the bottom in terms of efficiency, and also forcing another cell phone change and all the attendant physical waste.
I will say though that GRS has most definitely become an extremely weak blog, and I don't check it anymore. I found it after MMM(and long after it had been sold), and quickly went to the archives to vacuum up information, but the posts on the front of it are aimed at a very low level of conscious consumerism, and so readers of MMM might find that the information there is pretty weak.
