I deleted all my reddit comments at one point, but not before saving an offline copy for myself! The main difference with a personal diary and online comments

I deleted all my reddit comments at one point, but not before saving an offline copy for myself! The main difference with a personal diary and online comments is that the former is something only you and your closest companions have access too, versus the whole world for online comments in a public forum No one knows all of the countless purposes those comments could be used for in future decades. The extent to which such mundane daily interactions are now preserved is a totally new dynamic in human society, and I don't think a bit of caution is unreasonable
