This is what I thought of after reading your post: http://www.everydayminimalist.com/?p=1765
Minimalism? For me, yes, though I restrict my interest to (a) objects and (b) hassles and chores. If you can show me a way to get the same result but with less stuff, I'm interested. If you can show me that a chore I do is actually unnecessary, I'm interested. I'm not interested in simplifying my activities, though that comes more under simple living.
Simple living is what I am NOT interested in. I like to do what I enjoy and I don't buy all that stuff about completely absorbing yourself in the washing up or whatever - Zen Habits sort of stuff. Fine if you like that, but it's not for me.
Frugality does interest me, but a lot of blogs I've found are US-centric and don't help me in the UK. Sure, they may have lots of really neat hacks for US services, but that's no good when the system/laws here are different.
Green living I'm interested in but I wouldn't really read a blog about - I already recycle, try and use as little as I can etc. and there doesn't seem to be that much practical advice beyond that.
I used to think 'TBH 75% of minimalism blogs are crap'. Now, I realise that it's that minimalism is a very, very broad term that's applied to lots of different ideas, and it's just that I'm not interested in every category. That may well be how you feel too - I love lifehacker and Unclutterer because I find they give practical advice, not 'pseudo-intellectual bullshit' and 5-step programmes to (simplify your life/quit your day job/be happy) that start with '1. Embrace the day' or something like that.
