Well, there are these new ads that load prior to some threads being opened. Those "wait 15 seconds before thread loads or skip the ad" types. Generally, I find these very intrusive. I understand guru needs the money and all to run the site, but these ads aren't that useful on a forum when I'm openning like 15 threads at a time and I keep seeing those ads pop up.
Furthermore, on slower systems, this could really slow down load times of the forums, which prior to the server move a few months ago was already pretty bad. Do we really want to revert back to the old way where it took 90 seconds to load a thread?
Ads are necessary for any large gaming sites. Without ads guru, IGN, gamespot, Incgamers and more would not be here for the gaming community. From time to time we all must test out new ads, new campaigns, see what works what doesn't. This certainly isn't the first time we've switched up our advertising style or campaign. And it's the internet, people expect ads, any one who has ever surfed the web has received ads. This shouldn't be THAT big of a shock. It's a couple of seconds of ads, it's not every page load, and as you can see we welcome your constructive feedback and suggestions... as we always have.
