Hello. We didn't want to put people through a sign-up process AND then then ask them to fill out Weavrs profiles, so we opted for a 3rd party authentication. If we had used Twitter for Auth, then it becomes very confusing. There's Twitter accounts for Weavrs and for the User. If we had used Facebook, then people get really worried about privacy and Weavrs are not private beings. Nothing gets pulled from your Google account - just your username which you can change in Weavrs.
