So my general hope is to increase users on TON, whether that is something on the technical side or an app. Both I am determined to do. Just something big which is missing from TON, hopefully something unique to TON and has some Telegram use cases

yes i dont think ADNLand overlay network would achieve my desired effect

TON has a fresh ecosystem and there are lots of things you can develop over it. For example DEXs are mostly in testnet stage. You can view popular products on other chains that aren't present on TON and set a goal for developing one of them as in future TON will probably need such product, like various DeFi products (Aggregators, Farms, ...)

Yes that's true! I have all those written down - just thinking about something which would differentiate TON from everyone else. THink that would be useful too. Like how to leverage TON's uniqueness

Hmm, External message usecase would be interesting for that. for example user's can send messages to blockchain without need of an on-chain account (your contract receives the message and decides to pay the fees although with limited gas credit). This is a potential feature to attract users.
you can check https://ton.org/hack-a-ton-1 and see other ideas people brought in hackaton

interesting, whats the use case of this?

i like the micropayments pay per view idea, thats very cool
