Gentlemen, first, let me say that Digital Angel doesn't bother me. Anyone who knows the end times phrophecy knows that taking the mark of the beast will only happen three and a half years after Israel signs a peace treaty with the Antichrist, leader of the one world government, and it will not be something you can choose, unless you plan to live without your head. Until such time as there is peace in Israel, a one world government, a universal church, and no choice in the matter, I do not think it's prudent to worry about. When such a time comes about that all those things happen and taking such an implant is mandatory, then you should worry.
Still, how many of you non-believing free-thinker types don't find it at least a little interesting that at this time in history we find people trying to negotiate peace in Israel, the technology is here to make the mark of the beast possible, the belief in universal faith (all religous beliefs lead to the one true God), and the philosophy of one world government being so dominant? Not to be alarmist, but these are things that must be in place before The Tribulation can happen.
And there are people looking to make them happen. Organizations like the Club of Rome, who's sole goal is the unification of the global social and economic systems, comes to mind.
