There’s little in the way of fun in the ecosystem. Not a lot of true open source in the conventional sense, lots of Microsoft MVP consultant types with blogs promoting their services. Those websites look like time capsules from 2011. You won’t find many beautiful, “handcrafted” blogs on .NET topics. A perhaps bizarre metric, but it helped me well in gauging an ecosystem’s vibe (Rust, Go, Python and others pass that vibe check, for example).
Which is actually my main reason why I shill it here on HN - please, stop picking Go for the fun technical challenges. It's an exceedingly poor choice for that and you are making yourself a fool with it because you never looked at platform implementation details and capabilities to make an informed choice.
The "higher level managed Rust" you are looking for has always been C# even more so in the last couple of years due to proper low-level abstractions and performance it offers.
