I can share one.

Also for those interested in why not just use mastodon. In my opinion the atProtocol/bluesky is great because it allows you to easily have one account that can be used for any service. Imagine logging in to lemmy.world with your mastodon account. This is already possible on bluesky/atProtocol. Theres a number of apps that are like twitter spaces on atProtocol etc that work all with the same account.

Also the custom algorithm sharing is really great and helps the platform not have so much control on what you see.
