Whenever I get to that point, I find a new good blog, then read it from the beginning. That gives lots of material.
Imagine finding MMM today and having 2+ years of posts.
Tis strategy of finding one great blog and devouring it over weeks or months is much more enjoyable to me than finding 5 okay blogs and just reading the past few posts from each.
Regarding your first category, Mike over at lackingambition.com is a blog I have enjoyed in the past, though he rarely posts anymore (and in fact doesn't have that much overall, so reading his whole archives is pretty quick and enjoyable). You see a whole transition from beginning to FI.
Regarding the lifestyle category, JamesAltucher.com is quite good. Raptitude is also decent.
Read a few posts on those 3 and if they strike your fancy, dig back for more. I think you'll enjoy.
