Hey, @vimukthi.
Thanks for answering and providing the analysis. :)
I've wondered myself if the problem hasn't been blown out of proportion somewhat, since this is something that seemingly has been brought up by high SP whom at least some have been contributing to the very problem they purportedly now wanting to fix. So, we'll see.
I agree that actual curation by dApps rather than a usage reward would be better. The problem is, since STEEM isn't set up to fund dApps, we have them falling by the way or moving on somewhere else, or not manually curating because they can't keep up with costs. Or that's at least how I perceive things.
So, leaving more of this in the hands of the dApps is definitely an option, but those dApps need to have better business models or funding before they arrive here. Or, they will have to take advantage of the SPS, actually get funding, so they can continue to do what they're doing.
