But 30 years later, I think there are many reasons why you would not want to do this. (I also stopped doing so after 15.000 posts or so).
– you will grow and you will change opinions about things often 100 percent, the internet memory is however forever – you will enter in different careers and depending on the customer you would not want to be completely frank about every little thing you think or what your preferences are or what your experience is – in real life there are larger groups of persons with very different and often extreme viewpoints on either religious related, political related, culturally related etc viewpoints. This has grown and grown and has become a real life danger if you get picked up by some internet thread on some social media forum. This has changed from the 90’s where the internet was filled with intelligence and a hopeful view on the world. It is easy to fall into the trap of engaging in various discussions – you get children and often different social circles where you want to engage into blanco your children might not like at a certain stage you posting stuff (or pictures) (or opinions) – there are tons of frauds and criminal networks who gladly scrape everything you are from there not in the least for phishing
So more or less: because there is also the real world with the 20% of people who are on the fraud/extreme religious/extreme political/other criminals/dumb side and there is real life social interaction and personal growth the following 30 years where once you write something it becomes stone
