There's a new-ish website called "Plinky" which might help some people get their writing started, since every day, they provide a new prompt (like a question, or a challenge). I think this might be helpful when your brain really just needs to interact with someone or something in a new or different way. Plus, it's simple to use, and might be fun for you.
Their services include:
Add photos, maps, playlists and more. You can easily share your Plinky answers on Facebook, Twitter, WordPress, Tumblr, and most major blogging services. We know you've got something interesting to say. Plinky is here to help you say it in a fun and compelling way.
