Nendi Okorafor wrote a post. This would be where I mention and quote it.
And this link, goes to a blank page where Okorafor has deleted her post, her thoughts, tried to erase her history/actions online.
Unfortunately my trusty screencapture didn't catch her words. I don't know what happened. But googlecache still has her words, sans WS's comment. And I do have a confirmed screencapture of the cache.
It's been mentioned before that in the world of hyperlink essays and conversations - deleting is heinous. It's an attempt to silence the voice of the other person, and any conversations that happened in that space. It's an attempt to say 'That person is lying on me, because where are my words? You can't find them can you!'
Luckily, once something's on the internet, chances are - it's on there forever. So choose your words wisely - or at least be able to admit you made them.
