I use Wikipedia a lot. It’s one of those things that is just there, like the air that I breathe or the spot on my head that I scratch when I need to focus. Just there, always there.
But, as Sue Gardner says, not many people know that Wikipedia is run by a non-profit organisation of about fifty people. They need money for infrastructures, bills and salaries. They use your donations to keep Wikipedia there for all of us. I give them a tiny slice of my winter paycheck every year, hoping that they will still be there when I need them.
If you use Wikipedia, I encourage you to do the same, within your own possibilities. See here.
