I still use Ada daily for my personal projects after having used it at work. I find it compliments my thinking patterns well. My only gripe with it is that they ate too much of their own dog food at AdaCore and now it can be hard to install Ada and gprbuild (due to a circular dependency). Plus gprc stole libgpr and broke some stuff too.
They do list lemmy in the advanced “bubbling under” category. I guess they deem lemmy to be a work in progress, but not tildes?
