And what would you expect from a forum named Bitcointalk? We are lucky that this forum has involved and let other alts have their own sub section here and typically you will almost always see new projects popping out and there is really a few discussions going on aside from their ANN threads. From what I see aside from Bitcoin we will only see alts like ETH and the stablecoin Tether to be mentioned in other boards outside of the the alt section because ETH is the 2nd popular crypto and Tether being a stablecoin that can be traded in a crypto exchange and also its scandals. Cardano is not a bad crypto you are just looking at the wrong forum to see discussions or talks about it, maybe try visiting their subreddit page if you are looking for some content.
