Separate mailing list?

Should I create a separate mailing list for the NetNewsWire Pro beta?

I set up a poll on Yahoo Groups.

Arguments in favor of creating a new list: it may get a bit of traffic at times, and it will be off-topic for people who aren’t into beta-testing.

Arguments against creating a new list: one list is easier to follow. People don’t have to sign up for yet another mailing list.
