Though I rely on reviews for almost every purchase I make online, I'm gonna be honest and say that I've never left one myself. It's totally selfish behavior. I love looking at reviews, and they're an important part of my decision-making process. The people who leave them are my personal heroes, and they fuel the online shopping addiction I nurture. But I just don't have it in me to do it myself. It's a hassle and a thankless job. Like the people who make lyric videos on YouTube. We need them, we love them, but we give very little due to the people doing the grunt work. If everyone was like me, we'd never know which products are a scam, run small, or are perfect for a 5-year-old's birthday party. Society would collapse.
That said, the reviewers behind these posts answer to a different power. They're agents of chaos. Enjoy their folly.
