Here are several websites that I frequent (besides Facebook, which I am on way too much…). I’ll try to remember to add to this as I find more!
http://www.readwritethink.org/ This is the teacher contribution site for IRA. It contains some of the BEST resources for teaching and literacy education in general. It’s fairly user-friendly as well.
http://www.goodreads.com/ I do NOT use this site enough, but I really like the recommendations and categorizations of books. You can connect with other readers, look for books by category or genre, and sign up to win free books!
http://www.whatshouldireadnext.com/ If you want something more simplistic than GoodReads, use this one. You simply type in the name of a book or author you recently read and enjoyed, and it gives you multiple books that you also might like.
http://www.whataboutjesus.com/ Great site run by the WELS, WhatAboutJesus.com has audio devotions, answers to questions, a church location search engine, and lots of other tools for Christians to develop in their faith. Also, my church’s website might interest you: http://victoryofthelamb.com/
