Ask HN: Does Twitter push tweets to followers?

[michaelkscott]

How does twitter serve tweets to followers? In a typical CRUD app, it makes sense to store tweets in a `tweets` table and grab tweets from people that an account is following.

Does this scale at the size of twitter? If no, how do they do it?
