I am not a FB member, either, so there are several I cannot read, but I love
http://christaquiltsblog.com and the weekly newsletter put out by Martindale. There's always something interesting in them and Christa's blog usually has links to other bloggers who have their own ideas. It's fun to see how everyone does everything in their own way! Of course, reading them takes time away from sewing, but everyone needs to take a break now and then!
