I've launched a new Bible memorization service, LearnScripture.net.
I designed it with my congregation in mind, so it's child friendly, and also mobile-phone friendly, as well as being socially-oriented. Another unique selling point is good support for learning extended passages, rather than just individual verses.
Unlike memrise.com, who, according to their faq have no idea how they are going to make money, I decided to make this a paid service, so it will hopefully support itself and support me a bit too (I'm in a small church, so currently have to supplement my salary with freelance programming work).
You can follow it on twitter if you want to hear more.
