Tsk, tsk. They don't want you just reading the same few people. They want you to read the writers they're pushing this week. My 'For You' list is stuffed with things I don't have the remotest interest in but which are 'trending'. My 'Following' list can be static for days.

As to subscriptions, I have two email accounts, one I use for business (banking, online shopping, legal and government stuff). The other is mainly for fun, my fanfiction.net and Medium stuff. Keeps things nicely separate.
