What I think about .ton sites:

1. It must be easy to host site data using ton storage
2. It could be a great opportunity to show data from chain dirrectly using ton domain. For example, by default, we could show on site text wich we could store at the same cell where domain hosted (for example we could implement getter in related contract, which return site content, which could be shown by default). Thus, it will be possible to use TON domains, at least, to display data inside the contract. These ideas can be developed endlessly...
3. Right now many applications contain nested browser, it is importatn to add ability to show TON domains through this browsers. Such way, seems like it must be implemented browser version for easy integration in existing mobile applications

I am interested in developing TON DNS and with pleasure would help to develop it
