Some people say, even in this thread, to stick to things you like. Things you like may not always be popular. I said before that any niche is workable and I believe that but the people banking off adsense are probably doing many sites they don't know anything about, just what they can read online.
there are no "worst" subjects. if the subject will interest others, then its all good. it all matters on the content.
Nice input, thanks. YES - of COURSE I will write about things I LIKE to write about (DUH!). But just because I like the subject doesn't mean that these subjects generate ad revenue. So, let's stick to business, here. I also kinda assume that subjects that have been over-exposed, like making money at home, mesothelioma(sp?), and the like won't make ad money because it's too tough to get noticed. I've also been heard that blog subjects like politics and soft-core pron pics, don't make money on blogs because people that read these blogs do not click on ads, true?
I've heard the same - a blog about politics, regardless of political bent, can get lots of traffic and loads of comments but very little ad revenue. THANKS!!!
