Which kalam (both Sunni and Shia) still exist and how many people really study them? The ones I know of are:

- Athari (which is more like "no kalam" literalism if I understand this properly and is the same as ahl al-Hadith)
- Ash'ari (has Muturdi been absorbed into it?)
- For Shia I don't know a name other than "the Shia kalam"

Am I missing any and how many people really study them? How many Muslims would be ahl al-Hadith vs ahl al-Kalam?
