I like coffee! And I've written thousands and thousands of words while drinking them, then not been paid for those words.
As a freelance music writer, I've worked for Boiler Room, VICE, The Wire, and many others. I edit my own magazine (and now website), Right to Copy.
Right to Copy costs me at least 5 coffees a year to run, so help me out. :)
Full disclosure: I do have a full-time job, and I do earn good money. I'd love support for my creative work but, if you can only tip one artist today, pick one who's working hard at it full-time.
