Make what you need. Make tools, templates, etc. for yourself first, not for all of your friends or ”everyone“. If you design for some hypothetical user, they may not actually exist; if you make for yourself, you actually do exist. Make something that satisfies your needs (also known as scratch your own itch), and is compatible for others, e.g. by practicing POSSE, you benefit immediately, while staying connected to friends, without having to convince anyone. If and when others join the indieweb, you all benefit.
