Just click on the link and read it, you'll thank us (meaning the person that I pinned this from and the person who wrote it) later! This is the most plausible and intelligent theory about River somehow surviving after The Name of the Doctor that I have ever read and it's now my new Head-Canon. Trust me, just read it!!! *this is brilliant <--Exactly what they said!
Read It Later has now been rebranded as "Pocket". I used to use Instapaper all the time but now I think I'll be using Pocket instead. Pocket allows you to bookmark interesting articles on the go, and then read them at your liesure in a cleaned up format that removes ads and junk along the margins. You can even read articles online. I didn't care as much for the Read It Later version, but the new Pocket version is great. Check it out!
