I don’t want to annoy my visitors, so I’ve change the way the message works. Now, visitors will see a bar across the top of the site. If they click on that bar they will see a message. This bar will only load if you’re using AdBlock, visit at least 2 pages, and will stop loading after you visit 5 pages. The new bar requires cookies.
However, I’d like more feedback, so please take the time to fill out this poll.
