It looks like - as LoyceV found out earlier in the thread - that existing DT members were at a slight disadvantage in this initial DT1 reorg. Being in DT means that other users are less likely to include you in their custom lists explicitly.
Just 4 days ago, I was actually surprised how many people had included me:
OgNasty->LoyceV
TheQuin->LoyceV
Avirunes->LoyceV
teeGUMES->LoyceV
nutildah->LoyceV
mocacinno->LoyceV
HiDevin->LoyceV
Two of them had excluded OgNasty:
TheQuin-/>OgNasty
Avirunes-/>OgNasty
My assumption was they added me to get closer to what DT looks like to others.
