Yes, much more write-dominant. Apps which are built on top of the feeds can create issues, though. E.g., An obscure ticker pasted into a chat room with 500 people instantly starts monitoring in all their windows -- not just the static price (equiv to a RT), but the live feed. That would be as if A RT'd B and suddenly all of A's followers added B to their timeline. The degree to which that happens depends on how many features like that are integrated into the app.
