Simple. Facebook allows people to socialize via one convenient location.
It’s probably nothing special these days where there are any number of slick sites people can congregate. But back when I first started surfing (do they still use that word), having your own personalized community hub wasn’t possible. In fact, a simple (crude) personal webpage required a bit of skill and a lot of effort. I recall spending many many hours trying to master HTML code to create simple webpages. That kind of effort isn’t required anymore.
My wife passed away a few weeks ago. Of all the headache I had to endure making preparations for my wife’s burial, notifying friends and family was not one of them. I simply posted an “Event” to Facebook and the word was out.
Of course Facebook isn’t for everybody…but what is? Like it or not, it’s light years ahead of what was available during the age of dial up modems.
