I see the ability to purchase Steem Power as a future flaw in Steemit if the site and system become popular. Also, so what if investors who don't have the patience to wait two years are put off by the system; that's good because it helps ensure only those who have an interest in the success of the system rather than turning a profit will hold power here. I see Steemit as an important tool to knock down, or at least reduce the power of, mainstream social media sites who are in bed with all manner of "deplorables", from governments to Hollywood. It is also an important tool for the average person who knows nothing about the blockchain to place something into it for safe and accurate documentation. These are just some of the reasons I believe the interest of the system should be promoted over interest of taking profits and walking away.
Although I've not invested anything other than content in Steemit, I have given thought to how the system can be (ab)used and result in nothing more than another social media site/system filled with mindless pop "culture" garbage...primarily from entertainment outlets. One reason I came to Steemit was to get away from all the meaningless, vapid pop garbage pushed at me via marketing and trending on other sites.
The problem is this: Steem Power may be purchased using other currencies, thus leaving the door wide open to Hollywood to come in with their large bank accounts, buy Steem Power, and gain influence without doing anything at all. In turn, this influence would be used not to vote based on content, but on name and to give accounts of famous a foothold and reputation on Steemit.
If the system is going to be changed then make it so SP may only be gained via upvotes on content, or that power ups may only be done in amounts equal to the total Steem earned via content.
In reading some of the responses, I have indeed come across some who want to push entertainment. My above position is supported by something the individual said; that they don't like reading. Well, if you don't like reading and prefer entertainment, perhaps Facebook, Twitter, YouTube, and so on are a fit for you. You can find all the vapid entertainment there which will allow you to sit in your recliner with built-in commode, drink from a hose, watch 12 shows at once, and get angry when someone crashes through the wall and interrupts you "baitin".
If people want entertainment on Steemit that's great, but don't make it easy for existing bobbleheaded celebrities to infest it using a chunk of change but little to no effort. If you lean more towards the Jeffery Tucker crowd you may not see a problem with this, but not all of us lean his way.
I may be new here but I don't want to see Steemit ruined in much the same way California and other States were - by people fleeing the messes they created then turning their new homes into the same wrecks they fled from.
So, how does Steemit provide incentive for investors without making it easy for an infestation of "mainstream" entertainment to take root? Rather than trying to combat inflation (which should be done, but that's another subject) and tweak the power down period, make the change to Steem Power I mentioned and improve the site's UI. It's an unfortunate but true thing that if you give them shiny objects to play with they will come.
That is an interesting approach!
