Voting on anything is a private matter and should be top priority.
Once privacy is insured, then and only then should you continue with making your app better, to make topics or bills easier to vote on.
We’ve launched a private form of log in separate from Facebook. I hope that this addresses this concern.
That does NOT address the concern! There should be a totally and complete private setting with no public profile whatsoever and the default set to NOT share what you write to your congressmen as a comment. It's crazy that that's not already the default.
