For a short time I used to read a lot of blogs, but realized it was a waste of my time, most of the content was not very profitable (even though interesting)... Here are the 2 Blogs I find worth reading:
Thoughts On The Way (run by 3 Brothers from Charles Leiter's church): http://thoughtsonthewayblog.blogspot.com
Puritan Fellowship (run by a Brother from England): http://www.puritanfellowship.co
There are a few other good blogs I check on my lunch break at work as time permits, but I don't feel lead to post those right now... I would hate to tempt people to spend too much "free time" on endless blogs.
