I'm very happy to have seen it too! I'm going to need to make a list of people who's blog I need to hop onto regularly - yours included. :)
The lovely thing is, planet Kay isn't even too far fetched... I say let's continue taking steps towards it! Long live planet Kay!!
I made exactly such a list, it's definitely made my life easier, it's just too easy to miss my favorite people if I try to depend on the feed and memory alone.
We certainly could achieve a lot of the decentralization that planet Kay boasts, and I like to think I'm seeing into our future when I imagine these kinds of worlds. We will probably make a lot of this happen in the next decade at the rate things are really going now.
I believe that imagining the future as we want it to be is a powerful way to start bringing said future into existence. So I think you're right. :) It's a very exciting time to be alive.
My boys will all be turning into adults over the next decade, the mind boggles at the possibilities for them in their adult lives.
