Lifehacker: How to Clean Up Your Overwhelmed Gmail Inbox (by Hand). “There comes a time when enough is, quite simply, enough. I had been putting off the task of organizing my sprawling Gmail inbox for months, if not years. But when Lifehacker told me that we were going to have a Spring Cleaning week, I knew it was time. And I wasn’t going to waste precious hours trying to find apps or tools to do the task for me. I needed to Ron Swanson my inbox—roll up my sleeves, jump in, and manage the mess manually.” Wow.
