For the non-technical, can you explain the search engine you are building.

Also, what is your interest? Are you more interested in coding the search engine, or is the project irrelevant and you just wanted to stream yourself coding? In other words has the streaming of yourself coding become the project itself? If you are going to stream another project after the search engine, are you looking for ideas or do you have other pet projects you want to work on?

My suggestion, if you are trying to build an audience, crowd source your next project idea. Maybe give your audience a few ideas, allow them to nominate other ideas, and then have them vote. This way you build in the largest audience prior to beginning...and not unsurprisingly I have a project idea if you are interested.
