I wrote a blog post about learning a lot of characters in Skritter! This is for those of you who just feel you got to catch them all, or who really don’t want to rely on dictionaries when reading texts written for native speakers.
The post also contains information about a new deck in Skritter containing the 9933 most common characters, based on texts in simplified Chinese. It was inspired by this discussion started by @Farham. You can find the deck here, but please read the blog post itself or at least the deck description before diving in!
