1. To move forward at a slow or listless pace. You can still see my granddad pottering along into town each morning, the same way he's done every morning for the last 30 years. I hate it when people potter along in the bike lane when I'm trying to get to work each morning. Go to the countryside if you're looking for a leisurely cycle!
2. To continue or make progress at a steady, consistent pace, especially one that is neither particularly fast nor slow. The economy has been pottering along for a while now, and while it continues to make gains, it is not accelerating at the pace many economists say is needed to recover from the recession. Our business has been pottering along. We haven't exploded into success, but we're making good growth each month.
