My site is kind of a strange site, I break a lot of news and rumors. A number of news media places stay at my site day in and day out just refreshing looking for me to break some industry news.
If you look at my online stats at any time of the day there will be 3200 people online with only 1400 of them being registered logged in members, the rest are guests. I want to get them logged in as members. If they register and use an ad blocker I dont care, as now they are more apt to become an active member of the community.
