I think it is a really good idea, and take it all the way down to DT4+ with different colors to give more incentives to be positive for Bitcointalk..
I think it would be information overload. People would be less likely to notice.
I think eddie13 was sarcastic with that post.
What for? I would say it's better if the user discovers on their own whose Trust ratings and flags he can trust.
I am on the same page here. If someone does not know how the DT system works and does not know about his DT status then they really do not deserve to be in the DT list.
Bottom line: I really do not think we need such icon/image/or any indicator next to us to see by others users or for us that some of us are in the DT system.
Sorry about the off topic but here is something that I noticed. Some users will add you in their list and then they will PM you saying something like, I have added you to my TrustList .... .... ....
It's like they are asking indirectly to give them the favor (may be the wrong word) back. And I see this works very well too unfortunately.
How many of you have experienced this?
