I find myself asking this question more than 2-3 times an hour when I'm reading something online: WHY DOES THIS (especially some of the most professional) SITE HAVE TYPOS?! Surely they reread it for errors at least once before they published it, right? Right?! Let me save you the risk of looking unprofessional and rushed in your publishing work. By carefully inspecting pre-released content or posts, I can find the smallest "ie" switch or punctuation error that may cause your audience to think your site, product, or service isn't worth their time or money.
