Well, this list is deceiving and doesn't feature most dapps that are heavily used. Take Tronbet - it has about 400k transactions alone (had days with 1M+) and more users than Steemit. This list only looks good for Steemit, when you remove the top dapps from other chains. Yes, most of them are gambling, but wait for some weeks and you'll see social media dapps shooting to the top there too.
