On the one hand, for a humor strip of their kind, that's great thinking. On the other hand--nothing new. The better of the story-based webcomics divide their stuff into chapters or titled arcs, and you can often see how they've plotted things out for the future. The benefitial difference likely being, when a story-based comic is halted by its creator, you're left with dangling plot threads or character arcs that didn't get to see fruition, whereas with a strip like this, if they'd ever need to close the doors, they could probably wrap it up with whatever season they're on.
