Sequel.

Instead of only sharing the highlights with everyone, Sequel lets you share many different things with different people, without needing to create groups or fiddle with settings.

Create public or private channels for whatever you want to share updates about — e.g. music, travel, cooking, politics, work, or anything.

Other people browse your channels and follow the ones they want in their feeds (approval is required to see and follow private channels).

Post as much as you like to a channel, safe in the knowledge that you know who’s following and they’re interested in the topic. Or just post for yourself, like a journal — only you can see your channels’ followers.
