Do you guys think there's any realistic hope today (not accounting for what kind of horrible stuff might be possible in the future) of being able to keep your 'genuine' online activities separated from your public facing, sanitized ones? Such that no company's HR department would be able to tie your real life identity to your real online activities? I imagine it could be possible if you're serious and rigorous about it.

Or am I being naïve for even entertaining such a thought?
