Yes I agree, one way or another due to the algorithmic nature of the internet and indeed social media we're all to varying degrees being pushed towards echo chambers and I feel that is very dangerous to a cohesive society. Equally, I have extensively written about how this is being used to ferment division. Within my writing I make sure that I discuss a broad and diverse range of topics and I always remain true to myself. Outside of steemit I also have a very eclectic range of interests and indeed friends, but yes I can certainly see where you're coming from as I have highlighted similar concerns.
No problem, in regards to the #nobidbot i think it's a great idea and when I get the time I may also write a post pointing people in it's direction.
