The conundrum of Social Media and Time-shifting

Two things people like:

• TV time-shifting a la Tivo, BBC iPlayer or Sky+. It's brilliant, pause/rewind live TV, record a show whilst watching another, you know how it works, we wouldn't be without it.
• Social Networking during TV shows, twittering about X-Factor, facebooking on how bad they're dancing on Strictly, whatever, it really does add to the experience. Again, increasingly people wouldn't be without it.

Now, here's the kicker: These two things people love are fundamentally incompatible. If you're watching a time-shifted show then the web2.0 experience is impossible. Even a few minutes pause for a quick toilet trip means social networking moves from being a great part of the experience to becoming a source of irritating spoilers.

Is there any way the two can come together again once the viewer has done any kind of time-shift? I can see the idea of time-shifting web2.0 experiences alongside the time-shifted show, but that's going to be a one-way street - certainly it can no longer be an interactive opportunity.

Acknowledging that read-only is possible, can the web2.0 experience be linked to the time-shifted show itself? When you start to think about it, the scope of the problem gets very big, very quickly because of the variety of ways in which time-shifting now happens and the sources from which people get their time-shifting.

So, the question is: Will people go back to watching programmed TV rather than time-shifted TV so they can take part in social media associated with the programme? Maybe, if its worth it. If I was a TV channel exec I'd be driving hard at getting the social media element of the programme because it's the best way to retain an audience in these fragmented viewing times.
