The nature of software development and internet communities has always been transient - frameworks and projects and websites have all come and gone. Despite how unlikely it may seem, even Facebook is not immune to becoming dust in the wind someday. God knows I've started my fair share of hobby projects and left them behind in states ranging from broken to buggy, so I should be the last person to throw stones. I know how it feels to just hit a complete motivational brick wall, or to have so many other things come up in life that my little project is the last thing on my mind.
For as long as I can remember, from the days of PHP bulletin boards to Reddit to kbin, I've never had only a single profile. So I think it's not a bad idea to prepare for the possibility that kbin doesn't last forever - literally nothing does. Nor do I think that's a foregone conclusion! But even if Ernest has moved on, or he's tied down by other matters, I think what he built is inspiring. I legitimately believe that kbin is cool tech, far far cooler than Bitcoin or VR or AI. Maybe someone else spins up a kbin instance, or mbin becomes the new de facto standard, but I don't mind running this account for as long kbin.social sticks around... no matter how many 503's I see lol.
