Don't panic. You've made a great thing and credit is due, but at the same time you're in the middle of what could just be a brief peak of interest. The odds are good that it won't always be like this (unless you want it to.) Your graph reminded me of a scene from The Simpsons where 'Disco Stu' presents a graph entitled "Sales of Disco Records, 1976-1977" showing a massive upward swing. Seeking investment for his idea, Stu indicates "If these trends continue... aaayyyy!" Not trying to talk you down at all - but if this level of interest is unwelcome to you, the chances are good that it will get better. Most things run out of momentum pretty quickly if you're not actively keeping the ball bouncing.
