I suggest you take your algorithm and apply it to other niches. There might be good horizontal scalability there. For example why not try to crawl photography sites to discover popular photos and sort them by style or "taste" You could then create your own photo discovery service and call it Find my Style or something like that. There are two ways to do this, you can either directly scan the photos looking for graphical patterns or you could analyze the text into which the photo is posted.
