As someone who is intensely interested in memory and mnemonics, I always welcome new tools. The site looks great for being build in 24 hrs and I like the idea of a web-based tool for memorization. However, I do think the offer could use some work. As some other people have pointed out, SMS, email and Push notifications might get out of hand very quickly.

I think you have to consider that most people are using tools like Anki to memorize larger sets of data rather than the names of a few people or a nice quote. Tools like push notifications and text messages are just not an efficient way to digest that much information. I wouldn't mind getting a quote pushed out to me a few times in a day, but compound that by 100 or more items to memorize and suddenly your phone is blowing up every 3 seconds. No bueno.

If I were in your shoes, I would do away with the push, email and SMS notifications altogether. I like the idea of clipping items from around the web, because that actually solves one of the biggest pains of using Anki, which is organizing and typing all your items into the program (assuming there isn't already a stack available). You could even allow users to "clip" to a specific notebook to better organize their items.

Instead of sending notifications, I'd create a spaced-repetition mobile app and/or web app that allowed users to access their clipped items. That way, users can access your tool at their own discretion, but still get the benefit of having a tool to gather their information.

Anyhow, that's my 2 cents. Great job and good luck!
