I did not realise releasing Twitter handles that are not in use for long would actually be an issue. I understand Dave Winer’s point around link rot. But that exactly is the reason why people should own personal spaces and share everything that matters to them only there.
Also, while linking to something external, it preferably be a website. Because Twitter and others just rent us spaces for our thoughts on their platforms. It is too much to expect from theses businesses to not lend them ever to anyone else. Just own your space and let the lights on as long as you want.
I am sure link rot is a problem that’s not really very high on the list of issues that face these guys. Neither is the goal to be a better citizen of the larger web.
