I disagree with the op. This is historical data and includes all kinds of interesting content. Even if severely uninteresting today it may still be really valuable 40 years from now as part of research into colloquial language, design, trends, influence of events etc.
Same reason why notes taken by random people 250 years ago are really valuable to historians today, even if it's just a todo list
