First of all, I didn't say that I have no experience. I registered on Webmaster world a year ago, so I have some experience.
1) Telecommunications - I am an engineer. There is one post that gives me $5-10 a day, it is about cable systems and their analysis. Some huge sites are linking to it, so my blog is the first in Google and Yahoo for good keywords, it also gets traffic from these huge sites.
2) Electronics - mp3, videocameras etc. Reviews and other interesting stuff. Other blogger link to me, I was commenting their posts for some time and now they all put a link to my blog on their main page.
3) About car - this is the main money earning blog ($20-30 per day). I write there not about new cars, but about repair, insurance and driving.
4) Blog about how to earn on adsense and blog - gives $5 per day
I have 1600 uniques per day, because I am the first for some keywords. Many people told me that I will get sandboxed soon.
I just wanted to tell newbies that they also can earn money. I really did not think that I will get $50 a day.
I was a good commentator. So some bloggers are my friends, that is why I got many links to my blogs.
I hope to write "I am now at $300 a day, and you're all idiots!" some time =) But for now I think that $50 is a limit, traffic is growing slowly.
