I think it is better to support the sites you like and avoid those that you do not, than to leach from all sites without discretion.

(I have no idea what moistgorilla's issue with kotaku may be.)

I support sites that I like (RockPaperShotgun, 4chan) by directly giving them money, so that I am the customer, rather than the product being sold.

That, and the number of high profile incidents where attackers sneak Flash 0day exploits into ad networks, are the reasons why I block ads.

I don't deliberately block ads, but I do block Flash and Javascript for that reason. (If you want me to see your ads, make them work without Javascript, thankyou very much.)

That would means ads would be blocking page load, with javascript loaded ads, you can have the ad load asynchronously to the page.
