After receiving a devastating amount of comment spam in the last couple of days, I have decided to close all commenting functionality, at least temporarily, on this site. If you want to discuss or comment on anything, please send me an e-mail. I would love to re-post your thoughts on the website! It’s sad that it has come down to this, but I never received as much comments as I did e-mails anyway. Thanks for your understanding, and let’s keep in touch over e-mail (or ResearchGate)!
