Definatelly!!! You dont even need to invest any money for a domain, hosting e.t.c. See http://labnol.blogspot.com is making over $6000. Here is a video from CNN IBN report
Bloggers make money . Any kinda website makes money if it attracts visitors and a good blog surely attracts many.
Blogs can make money just like any other site. I know couple blogs that are ranked in top 5000 on alexa and get tons of hits. If you can get traffic to your site you will make money!
There are different kinds of free and self-hosted blogging software out there: blogger.com, wordpress.com, typepad.com among others. And then there are different themes for all of them. Hence they all look different.
I can say I have a few niche blogs and a few of them have made some nice pocket change. $xx to low $xxx each. So yes blogging is nice money. It wont pay all the bills and it will be more than just buying dinner on Friday nights either. If you know how to market yourself and if you have either a network of blogs on different IP's or niche blogs/with PR and/or traffic you will make some nice pocket change.
It depends on how you market them and/or if they are niche blogs. Than there are those who have PR vs. Traffic. So it depends on what you want or need. Some sell cheap up to $3000+ blogposts so like I said, It depends niche vs general. Traffic vs. backlinks.
I use blog to put interesting/useful articles for my visitors. I don't care about profits much, not at this point.
Blogger does pay you off well if you keep on updating the article daily of frequently, i am happy to use blogger and get few bucks extra.
