I got a new website, no design really. Its a simple and enjoyable idea. Will it work without a domain name? I don't know if the idea would depend on the domain... Have a quick look and see whether you think i should invest in a domain first... www.sitesong.blogspot.com
Do u think a blog would help u get at least 200$ ? When u are thinking to get 20000$ from a blog, u could invest 20$ for a website and make it more intresting I don't think it is
Not a good Idea, find something else then a blog, no one have time to read this days, only important unique things that worth is readable .
Of course it's best if you can get your own domain but I personally see nothing wrong with blogging. But this is coming from someone who has 5 blogs at blogger.com If I had the $ I'd get my own domain, but I'd still have blogs (some of which would be hosted @ blogger.com).
