@junho Depending on how you interpret Mastodon's internal systems, this should be impossible. After all, even the Federated Feed is limited in how much of the Fediverse it can access all at once. There's also nothing stopping you from simply scrolling through the feed slowly instead of sitting at the top and reading things as they come in-- even now, bigger instances have unreadable feeds in that sense.

As for ram usage, that's not a problem so long as they site is properly maintained. The only site I've seen with that problem is tumblr, and that site is such a mess that it's no mystery why it has problems loading things.
