On one hand I do want to support sites that I like and I know that for many this occurs through advertising.
On the other hand, I am honestly confused by what the web looks like with ads. Its been so long since the very first thing I did on any new computer, vm, or even non-technically inclined friend's machine wasn't to install ad block.
In many cases this wasn't really to not see the ads, but rather to make things appear where I'm used to seeing them. While I probably wouldn't find the "non-intrusive" ads themselves annoying. What I would find annoying is that the removal of the ads in many cases changes the layout of the page. All of a sudden what used to be the top right "module" maybe with recent posts or something is now the middle right module with an ad above it. Or even worse, some div that i'm used to seeing 'above the fold' now requires scrolling to see. All of a sudden my intuition and learned behavior for the interface has changed.
