Two different questions so two separate answers:

1. necrothreads: When I am on mobile it is a lite-site so I see no dates of any kind. People new to the forums will have no idea how old some threads are. Even people who have been around a while may get caught.

2. fresh enquiry: yes, I agree. But, we will still get this. I did this in my early days, too *hangs head* oh well.
