RE: Why Steemit/STEEM will fail.
If the number of comments plankton can make in a 5 day period was to stay as ridiculously low as it is right now, you're right. This place would be finished. You can't grow like that. No new user would stick around.
Supposedly this is also a part of the "transition pains" and will be adjusted by next week.
I've been trying to find out what the actual intended number of comments a person can make for a given SP, what "the new normal" is supposed to look like on this score, but no witness I've asked has as yet answered that one.
It would appear the system is "calibrating" what each action should cost in RCs. So maybe no one knows and something is supposed to tell us what's fair?
If 2 comments per 5 days is "fair" when someone has only 15 SP (what it is right now), then they need to figure out some progressive "taxation" on here, whereby those with high SP subsidize the resource usage of those with low SP (those still running on delegated SP from when they joined). Otherwise this platform isn't going to exist for any of us.
