I am using bloglovin' and tumblr!   This blog and blog reader is easy to learn and had a lot of information! Tumblr
I am following schoollibraryjournal, librarianproblems, elmirahslibrary, childitfan, and neverwithoutabook!  They all had great book reviews and had library ideas that would help every librarian.  The one I really liked was neverwithoutabook, it had books for all ages.
