I don't think a sticky is a good idea. All it does is give validity to people spamming new chains that really don't do much. A chain with a good idea that actually improves upon something will stand out on it's own.
I don't understand. This is the alt-currency forum ... where people are encouraged to think of innovations in the form of alternative currencies (that's what I gathered, at least).
If this is not made sticky, odds are that if a legitimate idea does get designed, its author will not find this RFC, and will not follow it. This will lead to unnecessary problems because the RFC is designed to help people launch successful currencies. People will forget to properly announce their chains, release testnets first, properly version the releases...
All the RFC does is formalize a set of best practices, that's all. I don't see how its existence as a sticky will encourage the creation of more ScamCoins.
