I want to build a website with a small but loyal community around it. But I guess to build a nice website one also need to be passionate about the topic they are building the website around. I am interested in these topics
1.Television - I watch a lot of tv shows and can write extensively about them.
5. History - Now I don't really know much history but I love to read history. But since I am not an academic how can I build a website around this topic that can attract visitors and we can develop an online community?
6. Social Media and the web in general - I like to talk about the developments in web technologies, and how web is transforming and how it is transforming the society.
I am thinking that I will keep the community portion of my website on Facebook by using facebook pages, comments, etc.
I would like to know which one these topics has
1. Less competition
2. More advertisers
3. More passionate following
If you were me which topic you will choose to build upon and why?
