DT has become less relevant now that the merit system has been introduced.
I hardly know shit about the trust system, except that I see that it is a link that I can click on in my profile.
And I can understand if you did a trade (or planning a trade) with someone why a trust rating might be helpful, but perhaps in the end, a more decentralized system of trust will be transformed into the merit system, which like you imply could cause the trust system to become less and less relevant because it seems that the way trust is set up has become a bit of a clusterfuck of gaming and drama.. and hardly anyone wants to get involved with inside politics, except perhaps scammers who are attempting to game the system, and even those negatively or positively affected by insider politics will frequently get worn out and frustrated by how complicated and dramatic systemic relationships of relative power can become and difficulties for laymen and even insiders to attempt to sort the accurate information from the misinformation.
