More users really need to set their trust lists, DT is increasing at a very slow pace right now and looking at a few different users custom lists DT should be larger than it is right now.
Although I agree more users should make a custom list, I don't think DT has to grow much bigger. I'm working on an overview of who's on DT2 now, and it's a very long list.
Copy that, I thought there were like 50 DT1 members and thought it could be nice to have around 100 or so but that is based off of nothing and DT2 is probably just as sufficient. Looking forward to that overview!
