Advertising: How Do You Feel?

Today I just wanna ask you guys a question: How do you feel about advertising? We see it everywhere - TV (if you have it), Movies, Billboards, Websites, Blogs... but how do you feel about it? Do you think there's a tasteful way to advertise anything, or do you consider it "gaudy" and "selling out" whenever you see it?

Personally, I really don't mind blogs that advertise. I click on the ads at Goodreads - I'm just super careful and only click on ads that I know won't hit me with a virus. I'm wary of some of them, and others I just have to roll my eyes at. (Do people really click on Viagra ads? I mean, seriously.)

But I'm not opposed to them. I see all kinds of blogs where it's just nothing but ads, or the ads are completely hidden (in the footer, hard to find, etc). And I wonder if those do any good. Do people read the blogs that are all adspace? (I mean, I assume that folks do, otherwise they wouldn't be advertising...right?)

I'm asking you guys this question to kind of feel you out a bit - I'm kind of thinking about advertising, but I don't really know if it's the right move for me. So be as detailed as possible with all of your thoughts - I don't care if Disqus truncates your comment! Just let me know what you think of it. :)

Do you think there's a tasteful way to advertise? Do bloggers lose all credibility for you when they advertise?
