Patient portals: does can mean should?

Check out a post of mine on KevinMD.com, with a lively comment thread. It includes this question:

How do we make sure that the patients who are actually using the EMR reflect the entire population?

My favorite comment so far:

Techie: If we can do it , we should do it.

Doctor: If we should do it, we should do it.

Patient: Did someone do something?
