Echo-chambers have their own special kind of ugly, Democratic Underground being an extreme example. Less extreme, echo chambers encourage laziness of thought and confirmation bias based choices of information sources (rampant on DU and the latter exhibited on some conservative discussion sites). Treehouse and Breitbart are nowhere near that league, though. I take the latter with a grain of salt and the former with a block of salt.
While I've been infesting TBR for less than 8 months, I do not think TBR has been anywhere near an "outlet for Democrat propaganda".
What made ToS a place of renown in its heyday was its ability to dissect news and prove it. There were enough members across the US to provide eye witness. There was enough expertise in various venues to speak with authority and provide relevant material.
I prefer that critical look, which *is here*, but often tamped down by those desiring an echo chamber, and others who just like throwing poo.
I prefer a critical look at 'our side' as being more important than being critical of the other - self policing used to be a feature in conservative circles. And looking at our own with a jaundiced eye provides metering (or rather, used to) that liberals lacked.
That is no longer the case - Neither in right-side journalism, nor in associated commentary.
And in that, where MSM could not be trusted, now nothing can be trusted.
