In Glitch, you can only learn X skills before "brain detoriation" kicks in, making it take longer. Without counting them manually, how do I know how many I have learned?
There's no direct way to do this, as fredley mentioned, but there are a few 'interesting' ways to do this.
Go to your profile page, look at the list of Latest Skills. It should look something like this:
Take the number you see on the right, then add up the number of icons displayed in the list.
Go to your skills page, then pop open your browser's console (Ctrl + Shift + K on Firefox, Ctrl + Shift + I on Chrome), and type in:
The number of learned skills should show up in the console
I have put together a tiny app with the API:
This will tell you how many skills you have learned, your current Better Learning level, and use this information to tell you your bonus/penalty to learn your next skill.
I've actually created a tool for doing this, called the Skillifier:
Not only does it tell you what you've learned, it shows you all the skills left and how much time it will take to learn each one in order. It shows the penalty percentage as well. In fact, it even shows a simple, "greedy" algorithm method of selecting the next skill, if time ordering is your priority. It also lets you prioritize skills that you'd prefer to learn early, and tracks prerequisites.
