Thanks for the update. I just checked the description of the CENT Community. The description now reads:
Cent tribe focuses on general content. You can find any content that interests you on the cent tag,
I recall the original description of the community said they wanted to focus on economics.
The topic of "economics" overlaps leofinance which focuses on crypto and finance. So, it is probably better off as a general content tag.
The unique thing about the CENT token is that it strives to be somewhat more stable than the other coins.
I will update my description of the CENT tag.
Communities Came Before Tribes
If you are wondering. HIVE released the "Community" feature before it releases HIVE-Engine. The communities tried to differentiate by focusing on different topics.
People added coins to the communities. This has caused many of the communities to become general use entities.
