Re: Just to be clear
Some content is temporary in nature.
E.g. two weeks ago I posted a picture of a burger with a note that says "and this joint have wi-fi". I knew that a friend of mine would be travelling the same way a week later and my picture gave him a feel for what kind of food to expect and what other services were available. And sure enough, a week later he made a stop at that location. I had also tested a shortcut which I told him about and he subsequently followed.
So a week ago my silly burger picture had value, but now it has become largely irrelevant and a year from now possibly just garbage. For all I know, the burger joint that opened in 2012 could be closed by the end of this year or they could radically change their menu or discontinue their offer of free wi-fi. The shortcut that was good this year might be terrible road work infested territory next summer. (in that area of the country they don't mess about -- they completely remove the asphalt leaving only large pebbles around that threaten to punch holes through your car)
In short: What has value today might be worthless next month. Someone might find my hamburger post (w/comments) worth a peek five years down the road, but I agree it is doubtful. Maybe I'll drive through there again some day and look at my posts from around that time to refresh my memory? Either way, why not store it in a sensible fashion?
