Brutal honesty: I have no intention of complying with GDPR. I do collect plenty of data from Europeans; but I am not a European, I do not directly use the data for commercial purposes (though I publish some of it) and I have no physical nexus in the EU.
I don't know if GDPR applies to me, but I can't be bothered either way. I've seen mixed interpretations about whether or not the data I collect, and my subsequent use of it, is relevant for GDPR. I don't care enough to spare the mental overhead. I welcome Europeans to contact me under the GDPR, but I'll likely ignore them completely unless I can be convinced any possible litigation would both impact me and actually come to pass.
Until I'm forced to do something, I'm not going to do anything at all about it. I don't expect that to be a popular opinion :)
