1. they aren't teenagers
2. they run websites that depend on ad revenue
3. they realize content creators need to get paid
So I installed an ad blocker, which actually made my 3g wifi hotspot usable over the summer. (Yes, I should stop visiting sites that get too annoying with aggressive ads, or I should just selectively block those sites).
It's one of those "I bet someone got a nice bonus for that" ideas that destroys user trust: http://blogs.msdn.com/b/oldnewthing/archive/2006/11/01/92244...
Slashdot's audio ads don't wait 10 minutes to start. Slashdot's much hated auto-refresh "feature" is to blame.
It periodically refreshes the page and brings you a new crop of ads, some of which might be audio ads.
The auto-refresh "feature" merely exists to increase their ad revenue. Nobody I know likes the auto-refresh feature, as it just causes you to lose your place on the page.
Slashdot's auto-refresh, which can't be disabled without some technical tinkering, is horrible, just horrible. I've left feedback that they should include an option to disable auto-refresh, but was ignored. I guess it's more profitable to ignore your users and force more ads on them.
I installed Adblock Plus and tweaked some Chrome settings to get the system to mostly ignore Slashdot's horrible auto-refresh. It still sometimes scrolls my page a bit, though, which is still annoying.
1. We want to speed up web-browsing experience.
2. Save internet bandwidth.
3. Are quite tired of highly intrusive, epileptic-seizure-inducing flash ads (some of them with audio).
4. Security reasons ( I personally use Noscript which has the side-effect of blocking ads)
5. Simply refuse to accept tracking cookies.
I wouldn't mind viewing unobtrusive text or image ads without tracking cookies (eg: StackOverflow) but very few websites actually implement those. I asked the owner of Phoronix.com about this a while back (who also seems to be having issues with the financial side of things)- Basically unobtrusive ads have much lower value than the obtrusive ones.
