I'm glad to see any updates to Gravatar. It's been around for a long, and was basically the first "link in bio" type of service I ever used. When I first started using it, I thought it was just a place where you could link your Wordpress sites to share. Now it seems the updates make it a more universal link in bio. I think they could make a really useful app if they added a feature where you could follow someone in the app, and if you follow them, you could opt in to receive news updates from their blogs within the app via RSS, and make the RSS and automatic thing. Not sure how easy that would be for them to implement though. But besides that, being able to follow people in the app, or even on the Gravatar site could be a useful way of building a network for content creators you want to follow.
