&gt; I&#x27;d love it if Facebook and Twitter had a rolling deletion period option - everything more than six months old is shredded forever, as far as the service is concerned.<p>I really like this idea. The biggest benefit is that it stops people expecting these services to act like an archive. With the current system it&#x27;s easy to think &quot;Oh I can just look this photo up again on Facebook if I want to&quot;. Instead we should be treating these services as publishing platforms while we maintain separate archival versions of our data.
