Where twitter went wrong with the new look

I have two things I very much dislike about the new twitter interface, and especially the iPhone App.

1) The new Discover page. Even though I decided to give it a fair go when it was introduced, it has so far delivered exactly zero useful results.
2) The 'Interactions' page. While the page might be useful when you are just starting out on twitter, once most of your real life friends are following you, whenever someone starts following you, 99 time out of a hundred it is a SPAM account, only following you in the vague hope of selling something. So it adds little or no value over 'just mentions'.
