add on

Obviously, the Snow/Snowden story was also a much later add-on—and one that reinforces the ideologically correct message.

One such add-on, Zerocoin, debuted at a San Francisco symposium in May.

As a result, it felt like an add-on, meant to artificially moisten another otherwise dry address.
