Whether its the best way or not depends on one's opinion. But it allows you to maintain a history of your deployments and things like creating tags when you deploy which is helpful for me.

Yes, Travis CI does allow you to do this. But it deploys every passing build, so you can't choose which builds should be released and which shouldn't.

I'm not aware of what others do but I sure hope they use a CI service to release a gem as it makes it easier to track what all is going in and maintaining a history.
