If you enjoy writing, reading and participation/engagement online, these crypto-social platforms offer as good a "savings account" as any out there.
Do you have to put in some effort? Sure you do.
It has actually saved my proverbial bacon, a number of times, from funding a much needed set of new tires for the truck, to paying off a property tax bill that was threatening a tax foreclosure.
So yes, it's a good investment — in more ways than one — if you have the money!
Interestingly, the steemit style account destroyed my ability to write and communicate online. I've pushed out thousands upon thousands of posts on free blogs.
The second I started thinking about the monetary value of posts, I lost my ability to write.
Of course, I was thinking about developing programs based on the blockchain model. All of my calculations show that, unless the blockchain is creating something of value, then more money most go into the chain than comes out of it; so I've become like a record player caught in a skip loop while I try to figure out how to make curation work.
It was Facebook that ruined my ability to write... I ended up with a sense of "why bother?" in the face of random character attacks being more commonplace than intelligent discourse.
That said, my best blogging days were really back in the late 1990s to about 2005 before Facebook and MySpace decided that inane smileys were a more appropriate form of engagement than actual dialogue.
I never did facebook. I was not into writing posts for my family. In contrast, I really enjoyed creating web sites with PHP and interfacing with the local community.
I think it would be possible to create a truly community focused site on a blockchain. The question is whether or not the reward structure enhances the site or if the rewards simply bring out bad behavior.
