I follow what I want to follow and an fine with a reasonable number of ads. I've counted and am throwing in the flag. Out of the first 15 items that come up in my feed 10 are ads. 66% ads! Its the same everyday. Thats numerically. Screen space is far worse since the ads often have large graphics. This includes ads by Twitter trying to tell me what to follow and what other people follow. I'm done. Deleted Twitter today.
