Every writer needs a place to sharpen their craft. Scribophile is one my personal favorites. I've included a number of screenshots below because a picture's worth a thousand words. This site wins simply because it makes writing fun. The entire experience is based on a rewards system. If you want to post a work for critique, then you have to earn Karma points by critiquing the work of others. You get all sorts of crafty titles along the way as you accumulate points, such as Pencil Pusher, my current status. The best part . . . occasionally you get to read some truly impressive writing while having other writers offer helpful critiques on your own work. I'm a fan. See for yourself. Check out the site or at least take a look at the screenshots below.
