Ask HN: Why can reddit users delete their old comments, but HN users can't?

Because they are two completely different websites.

> Why can reddit users delete their old comments, but HN users can't?

1. Because of the sometimes perverse and always unfair effect of deleting comments after 20 replies are attached.

2. Because HN commenters expect to be held to a higher standard of personal responsibility.

3. Because we should be obliged to explain our misstatements, not delete them.
