I’m super pumped for the vocab challenge!
What I’m studying
I’m aiming for 15-hours of study over the 22 days. I figure about 15 minutes/day will be spent clearing my due cards. The rest of the time will be spent studying 5-10 individual characters that I’m adding from the 台灣通用字彙 study decks @SkritterOlle made back in 2012. Target of around 5-minutes of active studying per new character depending on how familiar I’m am with it to customize definitions, study components, etc..
Other vocabularies will be coming from poems, songs, and articles I’m working on in conjunction with my 1-on-1 classes I take every week on italki. These words don’t get added daily since my usual flow for them is
- Learn them in context (articles, conversations, etc.)
- Write example sentences or short journal entries that my teacher corrects on Fridays
- Add the whole lot into Skritter
- Learn, Test, and then finally Review!
How I’m sharing progress publicly
I’ve got a personal studygram account over on Instagram just for Chinese stuff. I’ll be using the hashtags #skritterstudygram and #hcvocabchallenge on all the related posts. If anyone is interested in doing the same, consider following me and using the hashtags so we can be study buddies! 
Apart from that, I’ll naturally be posting updates on the actual Hacking Chinese challenge progress page. Gotta try and get that free Skritter!!! 
Here are the decks that Olle and I reference in the video chat for anyone interested.

Via Olle on YouTube. A word of warning, though: The last level is a beast in terms of content. It has roughly 2,000 characters in it and the last half contains many characters that educated native speakers recognize, but don’t use much or are very specific in how they are used. It can, of course, be debated how many characters one actually needs to learn and maintain, but for me personally, the limit seems to be around 5,000.
