The internet’s best resources are almost universally volunteer run and donation based, like Wikipedia and The Internet Archive. Every time a great resource is accidentally created by a for-profit company, it is eventually destroyed, like Flickr and Google Reader. Reddit could be what Usenet was supposed to be, a hub of internet-wide discussion on every topic imaginable, if it wasn’t also a private company forced to come up with a credible plan to make hosting discussions sound in any way like a profitable venture.
I would likely do the delete post as well but I will also download my posts and comments to archive somewhere. It’s very interesting to search something and then google send a reddit link to your older post. I don’t have that much impact anyway, it’s just for my personal amusement. (like sharing my old Monster Hunter achievement or etc, nothing serious.)
