Perhaps have multiple different upvote (and maybe downvote) types and allow individual guilds to decide which is appropriate for them to enable based on what kind of discussion guildowners want? Though that might make it feel too much like a crappy social media site with reactions and add difficulty in merging guilds into a coherently ranked front page. Maybe more appropriate for a federated approach than a single website. Otherwise I think the 2-upvote system is more interesting and useful, though there's more of a demand for and expectation of the traditional up-down system.
