Its so easy to get sucked into a thread only to discover it may be almost 9 years old! The OP in that thread who asked for some help so many years ago either got help or didn't and gave up, by now.
At the same time it can be fun to see what we hashed around years ago.
The problem is that I zoom past the date without registering it in my mind, and the thread or post seems current.
An old paper correspondance looks obviously old. Antiquated fonts and paper condition are givaways before you even see the date. But with computers old posts show up looking exactly like current threads, even with our current avatars.
So I thought it would be an idea to put older posts on a yellow background. For every year old a bit darker yellow or sepia toned. Every January 1 the colors shift so last year is always the lightest shade of yellow.
Oh well, this is the result of having too much coffee before 10 am. But I think its a cool idea.
