Thanks @cryptoriddler, I was wondering how to get my posts read, how to make some progress here on Steemit. I see some profiles are just spammers or scammers, trying to milk the system but not offering any creative or knowledgeable content. Some are probably bots or trolls or whatever, as you mentioned above.
So I appreciate your genuine sharing. I was approved quickly enough, but still learning what to actually do on the site to progress, to get readers, what to speak of votes or credits (secondary), so you have helped a lot.
