It does take time to produce 'good stuff' but if you like writing then the time taken to do it is negligible. If you enjoy writing and then if people show your appreciation, its a side benefit.
I for one am writing my memoirs of a particularly shitty part of my life , more for my daughter who gets a kick out of 'what dad used to do', but now I have a permanent record on the blockchain. I'm finding it both fun and liberating.
I think this is a nice thing to have. I write a diary for my daughter about her life. I hope one day she will have a chance to read it herself.
I think anyone can post something they enjoy here and it will be better than most of the crap offered.
