If you're seeing ads here you're seeing ads everywhere and they can be much more than annoying! I work at a place that has literally thousands of PCs. Our IT department URGES all of us to use an adblocker tool. I use Chrome w/Adblock Plus on ALL my machines. It works well and is free.
I seriously don't know how anyone surfs the web without an adblocker. I tried watching a youtube clip with a friend and ads kept popping up. I was like WTH is that? I never see any of that crap on any site.

I also don't do mobile browsing(especially here) but have heard the mobile version of Adblock Plus works OK.
