As a matter of fact, that 0.05 merit/post ratio is actually pretty decent for Altcoin Discussion as their total average since 2018 up until now is only 0.02. To put things into perpsective and to show how low that is, even Off Topic board has higher overall merit/post ratio (0.07) and we all know about generally poor quality of posts there.

Anyway, if you are curious about some other boards merit/post ratios, you can find them on Merit Dashboard.
