It would be awesome though if you help the community add Litecoin. That's why I made it a wiki. So anyone can add missing information. Crypto is so big now I definitely can't do it all.
So no, I don't think the majority will survive (hence the need for this project) but the survivors will be so astonishing and will give amazing returns.
E.g. : a page on PoW, a page on PoS (or possibly multiple pages for the different versions of PoS), any other similar mechanisms, ERC20, different styles of handling balances (e.g. Bitcoins UTXOs vs. Ethereum's using a merkle tree of balances), merkle trees in general, ways of doing anonymous transactions (e.g. Zksnarks and such), etc.
Edit: I mistakenly called ERC20 EIP20. I have corrected this.
Any plans to add live data?
That's precisely the problem... people will do anything to try to manipulate their favorite cryptocurrency. It's going to be an uphill battle trying to keep this unbiased.
