By.Calli, a pen name mr.calli, is a brand used by grappo. You can think of it as a nickname. calli deals with the functionality and aesthetics of all writing in the world. An article exists primarily to be read. If an article is poorly written, it can have huge consequences. For example, if you write a traffic sign with a blackletter that cannot be read quickly, people will wander a lot on the roads and consume more energy. If all people do this, national capital will suffer and this will lead to more consumption. Everyone must produce wisely to avoid consuming more. Global warming is a big problem and we can prevent it. Calli has brought good writing to the nft platform because she wants to draw attention to it.
