Administrivia: Shutting down comments for really old posts

The lifecycle of a blog-entry is, apparently, as follows:

- We write stuff on this here newfangled blog
- People either read it or they don’t
- People either choose to comment or they don’t
- A long time goes by
- Google picks up the entry
- Spammers heap their filth on the entry like seagull droppings on a new hat

Since this seems to only impact older entries – which folks rarely comment on anyway – from now on I’ll be disabling comments for the key offenders of spam entries (about 90 percent of spam comes from about 2 percent of entries.) Sorry to those rare folks who feel the sudden urge to comment on stuff from 2 years ago – but time waits for no one.
