ActiveSupport still has a wonderfully readable implementation:

Though I don't really use Rails that often any more, I still miss some of the niceties.

If something was less than 24 hours ago, there's a good chance that it was actually be "yesterday" rather than "today".

The peer post linking to someone else's solution that uses size appropriate scales seems better.
