Re: Social media no longer just for kids?
I've been using social media to keep track of products or manufacturers I like, as well as bands and artists I like. It's a nice source of information that way. All there for you, with your friends also helping in sharing that sort of stuff when they hit like etc.
I've also used it for promotion of my photography and photo retouching business. Which up until recently was easy to do, and beneficial. I was able to reach those that wanted my business but didn't yet know I existed or even know they wanted to pay someone to do what I do for them. FB have changed the rules though, so my reach is now 5% of what it use to be, and will remain that way until I pay them money to increase that reach (which isn't worth it atm).
It's also good to feel like you're a part of the lives of those who you were once close to, but have moved away...and life has it that you wouldn't pick up the phone to catch up with them anyway due to distance or cost, or the worry that they're busy with their new life and family. But you can see from a distance that things are happy, so you become happy for them. Or you see they need help, and can then pick up that phone.
It's also the best thing for those that require external gratification. If you're one of those types, and someone hits that like button on your photo or link, you'd probably smile big....on the flipside you might get depressed if no one clicks like or comments. lol.
Facebook has evolved over the years, also. It's most definitely changed from when it was University-invite-only, where you had to have a college email address, and know someone who was a part of FB and could send you an invite. There were much less adverts, and it was more about the people, what they were doing, or who (lol), than "products". It'll probably change again.
