No... no it doesn't. But that is probably because I never put any ads up on it, nor did I give people any way to give me money... Not that I get all that many visitors that aren't spam bots anyway...
I second this.. though I have a few random international folk that are not spam bots and a chunk of my family.. I am afraid if I put up ads and one is a malware in disguise that I will be getting a phone call to clean up the mess.
I guess, sorta. It really depends on how much time you dedicate to it. If you know what you're doing, and you dedicate enough time to it, I think it can at least get enough to pay for itself, if not earn you a few pennies in the process.
It's definitely proportional to the effort you put in to it. There are thousands of bloggers that make a living just from blogging, and probably tens of thousands more than make enough money on the side to pay for their vacations/hobbies/toys/etc.
I think for a lot of people, they start something they enjoy, then begin to understand how to monetize it correctly and earn money over time. There are some that set out with the intention of making money from the beginning, but I think they are probably in the minority.
My site does not pay for itself, nor do I want it to. I'm not really looking for publicity, and I don't even have ads on my site. When I write something I feel is important, I simply make sure it gets out to the ones I wish it to get out too. It's easy to get people to visit your site, through reddit and such depending on what you blog about and stuff.
Nope, though I've just really started the process of setting up my first actual blog site. I have no expectations though. It's just experimenting, a new virtual sandbox to mess around with for me.
I think the best way to look at it is that the cost/time associated with your blog (or any site you're responsible for) is really just an investment in yourself. Advance existing skills, learn new ones, throw in a little social networking on the side, and it could lead to some kind of a paycheck down the road.
