> 1 is an awesome idea and I'd love to hear more.

Basic idea is to use a federated blockchain platform to form a graph of students, teachers, employers and relevant government agencies. When a student gets a job and starts earning income, a percentage of the salary paid via the employer is sent to the education institution and teachers related to that student.

> 2 is wiktionary, I think?

Not exactly Wiktionary. Wiktionary is a static type of dictionary. What I envision is a more dynamic multi-lingual dictionary where there is link for a word from one language to other languages. That way users will be able to explore other languages and learn.
