I run one of the AIS stations that contributes to this. Of course, "RUN" is a bit of an overstatement, the little rPi unit basically just sits there unattended and feeds data received into the system without much need for any attention from me.

I am in the process of adding an uplink from my AIS650 on my boat to also send data received while underway, but need to finish up some other projects first.

I do not have much use for the commercial data side of this, but looking at past routes of various pleasure craft going to or from places I want to go can be informative for planning routes.
