While I work on my devRant client, I always end up thinking, "how would dfox do it for the backend".

Some of the functions I have include:
-fetching new rants, 250 at a time
-remembering the ones I've read and filtering those out (kinda similar to Algo)
-checking for updates from followed users and new notifications

My implementions are kinda spammy though part of it is because I need to use the existing API.

But even so, how would/does he implement these so all the users' requests don't end up bringing down the server, and efficiently store and retrieve everyone's view history?

My problems are small compared to his... How do you think and deal with problems at that scale though?
