I am a search guy and I would like you to succeed. But I don't get it. The name of the site is bland and makes me think you are a white label search service for websites. On the homepage it says "Open source search engine and search as a service for personal and independent websites." but it offers me to reason about why I (or anyone) would want to use it. The content it actually searches is random and of no real particular value as far as I can tell. Also, you are trying to avoid spam sites, but once you reach a certain size that's all you would see is people submitting spam sites. If you blocked people from submitting you would never get all the diamonds in the rough you are trying to expose.

You need to find an actual niche that solves a real problem people have and can understand and orient everything you do to tackling that. Then expand from there.
