The CDC now has two unique tools from the Web 2.0 World. eCards as health reminders is the first. Looks like they are adding new ones all the time but have a good variety in the archive. Everything from travel tips to the Olympics and fireworks safety.
They also have widgets and gadgets - currently there are two Google gadgets - flu updates and flu activity maps. CDC + Google = public health web.
How effective will these tools be? Unclear right now unless they take off through viral emails and links. Ha, Ha!
