All good things started as pet projects...as long as you maintain an interest in building the community you should do fine. Sponsorships and ad sells will come naturally when you establish an engaged audience. Work on building up the content that you curate, and like someone else mentioned maybe use any video editing and recording skills that you may have to create your own video content and commentary, that will give people a reason to come back on a regular basis. Also you should have an email newsletter signup to interact with users when they're not actively looking for new info.
