The only way to allow users to see what these new features are like is to turn them on. You can turn them off easy as pie, with the instructions that were posted before they were even turned on.

As far as I know, the only way you could even be getting new notifications from these tools is if you had previously hashtagged anything, @ tagged users (or been tagged by someone else), or followed people. And there was no way to add keyword alerts to a list before, so you couldn't have been notified of those at all.
