My mental model jumped from significant to large too easily, sorry about that.
What notifications were you seeing? I'm trying to think what I would receive that wasn't another user interacting with me and all I can recall is something along the lines of 'User1, User2, ..., all liked User3's Tweet' where User1 and User2 were people I followed. But it was very strange because every now and then I get those notifications for high profile accounts and other times it would be like two friends liked a third friends tweet. Those notifications were quite sporadic though and don't bother me in the least.
