I'm just curious - what was the main reason, that you started/stopped using a social network (like Facebook, Twitter, reddit, etc. ... and at last but absolutely not least - also Hubski ;-))? Friends, family (their opinion, their usage), trend or just out of curiosity?
Also, did you ever create profiles on social networks, just for the plain reason that your username you use elsewhere won't be taken there? To be honest, I did so on reddit.
If you don't talk to people, you will lose your mind. If you're isolated for any reason, self-imposed or otherwise, you'll seek out socialization wherever you can find it. Humans are social animals; we need social interaction to survive. Choosing bad friends hurts your mental health as much as choosing bad food hurts your physical health. It's important to surround yourself with good people, for that reason. There are more than a few popular social networks which are actively harmful to their participants. I think hubski is not one like that.
I joined Facebook when it was still new and required you to be in college to use it. I used it just to post dumb status updates and added people I knew from elementary school all the way up to college. I never had a MySpace account because I thought the site was ugly, but Facebook seemed like a MySpace that was easier on the eyes, because users couldn't customize their pages with ugly backgrounds and bad music. (There's something to be said for limiting user profile customization.) But I got sick of Facebook soon enough (not soon enough), finding that no one had much interesting to say, and I didn't really care about the latest baby or marriage or trip to Europe. Facebook was specifically meant to connect real life friends and family, and... well, what's the point, when you physically see them all the time anyway? For people I didn't see all the time, I didn't keep up with them, so having them as friends on Facebook served no function. I didn't realize I didn't like the concept of Facebook for a long time, I just thought I didn't like Facebook itself, and I looked for an alternative. I jumped on the G+ bandwagon, but it was only then that I discovered there was no point. The whole setup of those things was just not an interesting experience. I also joined LinkedIn ("the Facebook for business"... sigh...) because I was told to for professional reasons, and Twitter, which can be fun on occasion, but it was really upon checking out Digg that I discovered a very different breed of social media. Much more like a message board, discussing content with strangers (i.e. people who have an interest in the topic, rather than people who live nearby me or have the same blood), I felt like it was just a much more pleasant experience. I left Digg from that hexcode fiasco and settled on Reddit for a while, and recently made the switch to Hubski after the most recent Reddit bloodbath. I have, in the meantime, deleted my Facebook account, because who needs it? When I set my grandmother up with a Facebook account, I realized I hadn't even checked my own account for months, and it had felt great. So, away it went. I do still have plenty of those other accounts, but each tends to point to my blog. My Twitters are links to my blog posts half the time, and all of my G+ posts are that (because I use Blogger, I have the option to automatically post to G+, otherwise it would see no use at all... guess Google can count me as an "active" G+ user). I've got a deviantArt profile, too, and all it really does is say "plz go to blag kthx". Someday, someday, maybe I'll get more real comments on my blog than spam comments, but until then... blog? Blog? Yes, blog?
I pretty much just use Facebook for poetry events and to see if any friends have any plans for the night. I rarely post statuses or engage in conversations. I got a Facebook at the start of college because it was just the cool thing to do back then. As for other social media sites, I am not active at all.
I think I maybe posted 3 things on Facebook. Never had another social media profile (I don't consider reddit social media a la Facebook/Twitter.) I have posted on reddit, but only in a few specific game subreddits. I don't see a need for Facebook, nor do I have a desire to use it. If someone needs to contact me, they can call or text me.
I joined Facebook because apparently these days Facebook messenger is all anyone uses for communication?! I'm pretty sure I haven't posted anything yet though.
