We (https://raygun.com https://raygun.com) use a lot of .NET on the server side. We also use golang, node and a few other things, but a lot of .NET, specifically with C#. We're very excited about being able to run on Linux. There's plenty of our back end worker processes that are in C# and being able to move them to Linux will be a big win for us (manageability, cost, etc). I'm not sure what you consider a significant user base, but we do have 40k+ devs on our platform, and we process billions of interactions and software exceptions every month from many of the top 100 web sites and apps globally.
