Any information created by humans is part of our "culture". You may consider it of no value, but someone else may beg to differ.
I went to a fantastic talk a few years ago at the British Library about digitizing a substantial quantity historic Australian newspapers. It was amazing to be able to read funeral announcements, product advertisements and other signals from the past showing us Australian culture from the 1800s.
Since we leave much less behind in terms of physical assets (personal letters, postcards, personal diaries), we should at least aspire to archive more from the digital realm, or to future historians we'd look like a blank century.
