That is probably the right way to get people started, assuming they want to do their browsing on their phone. The barrier to entry for those who just download Voyager is so low that it might help make up for a lack of understanding about other features.

Personally I find it worthwhile just for the extra civility there is here in the comments and the peace of mind I get from knowing that I’m probably interacting with real people rather than bots.
