Are we an action blog or a discussion blog?
When we register with daily kos, we currently need only supply a confidential email address.
If when registering or re-registering, we all gave up the zip code where we voted, a powerful database of voters and districts could be collected.
Kos could then run a program to identify members to contact within various districts as district specific issues arose.
Would disclosing our zip code be an invasion of our privacy, that outweighs the potential for political action?
