I have used gkrellm since 1998 when my preferred wm was blackbox and playing MP3s in xmms was cool. Still run it today on Cinnamon. RIP Bill and thanks for the OSS contribution of a lifetime!
It seems it's a last name of an author and not just the arch nemesis of Sherlock Holmes. ;)
An interesting development is that there is generally an increased acceptance for psychiatric diagnoses. More are accepting that just as the pancreas may stop delivering insulin, the brain may fail to uphold the proper seretonin levels. Unfortunately it is not as simple as that, fixing seretonin or any other substance is like pouring oil over an engine and hope that it reaches the target. Still, I'm sure that we will see a huge change as true targeted treatments are no longer just sci-fi. Getting people to the right specialist is until then a good start.
