It's still the platform if you are in the counter strike scene. It's where all the pros and business insiders are. If you want updates, scoops, if you're looking for a team or want to learn about tournaments in your area, you have to be on Twitter. It sucks. For me, personally, this just means I don't follow the Counter-Strike scene anymore :/
Yeah. Just how it goes unfortunately. Consumer buy-in is vastly underrepresented in the technology world. Google, Facebook, Twitter, etc have all leveraged customer and community laziness to push the boundaries without much blowback. If Elon's tenure over twitter/xitter shows anything, it's that.
