M.G.
I started out ok and then at one point the ads got really bad, and I think everyone found them very bad at the same time. They were playing videos. The videos were slowing down my laptop terribly and causing problems for me. Moms recommended Adblock and I've used that and Adblock Plus (right now using the Plus version for some reason it's working better for me).
I know the site needs ads to run (to pay for itself) but for me, it was so frustrating - much more so than any other site/web page I visited.
