I loved the post and was not done reading your concluding statements before I got a giant pop-up that asked me to give you my e-mail to read the exact same post I was reading. I understand pop-ups like that work for making mailing lists but can you at least make it come at the bottom of the page not in the middle of the last paragraph? That combined with clicking the "No thanks, I don't want to grow my business" button being the only way to get out of it made me leave the page without even finishing your article.
