Sure there's a lot of Bitcoin content, but there's a lot of non-Bitcoin content too. Permaculture, crafts & art, music, general ranting... If you find some topics specifically lacking, you can always start talking about them yourself. I have people in my follow list that never or very rarely would speak about Bitcoin. 

I agree it can be challenging to curate the feed out of any Bitcoin content atm, but imo that's a phase that will eventually pass as userbase grows. 

 The other content is few and far between. And even those users are incentivised to appeal to bitcointwitter tastes, as it's the dominant culture here. And it seems like a feedback loop and is very much solidifying who is here and what gets posted and engaged with. Just from my limited observations obvs
