My assumption on any changes Twitter makes is that it's powered by the hope of future ad revenue. I see that potential for ads in Moments. I would guess Hearts will get tweaked in the future to behave in a way that will make them something of value to brands (at least, Twitter hopes). Similar to brands spending money for Facebook Likes (and thus getting their logos in people's feeds), I see Hearts as a first move towards a similar feature/concept. Personally I like this change (as it is now) because I've only ever used stars as a "like" button, knowing people on the other end see that in their timeline. It's a very useful social tool for acknowledgement.
