It's not too intrusive but it shows up very frequently even if I click the link to opt out of it. I've cleared my cache and tried a different browser and still have the same issue. I can see it wreaking havoc if someone is accessing the site via a phone or tablet and not using the app. Some of those pop over ads are pretty hard to get rid of on small touch screens.
The kicker is that I run Ad Block Plus (long time user) and it got past that.
Like I said it's not a huge deal but it will get annoying if it continues.
I'll pass this info on to the marketing team and left them know that the opt out function is not working properly. I can understand you seeing it once, but not repeatedly if you click the opt out link.
