I now live in a country where Facebook is a major part of how people function online. I deleted my profile and stayed off for 2 years when I still lived in the US, but here it's more vital to have one unfortunately.
Since everyone is on it, it would make sense that not using it would "exclude" you or a social standard or norm.
There are two sides to this.
First, I don't since exchanging on facebook is relevant or meaningful social exchange. Teamspeak or skype are more meaningful, but facebook only brings delayed text, photo and video, while real time matters more.
The second side is that as I've discussed already, there are no discovery feature on facebook. You don't make new friends thanks to facebook, you only do with Tinder, meetup, Uber, etc. The friendship relation in facebook is one of exclusivity. I don't think facebook events or groups are really attractive to users, or really do create new friendships, beyond the classical scenario of real life meeting. If you make new friends, it's not really thanks to facebook, because organizing an event can be done on any other platform, or even by email.
So it's true that user base matters a lot, but facebook seems to have little to no usefulness. It's just for messaging, posting photos, event exposure. It's just a very large myspace, with improved features, but it brings nothing new to the table.
You mean, except for FB Messenger (and Whatsapp, which should be included if one it talking about the company practices).
The second side is that as I've discussed already, there are no discovery feature on facebook.
I'm not a user, but AFAIK it does suggest friends to you. Plus, you often interact with friends-of-friends (e.g. through comments on posts of your friends), which does allow you to discover new people.
At that point, we could give up on privacy altogether.
Network effect and low friction is why it's useful but if everyone was on some other platform where I could find them by name I'd happily switch given I mostly use it for messaging and event planning.
After 10 days clean, buy yourself a beer.
I don't know if you have a fanpage or anything, but if you just do it personally, I have far more reach sharing on HN, reddit, and my personal site compared to Facebook.
The problem with Facebook other than bad privacy is that it doesn't take much to press the like button. Someone clicking like doesn't mean shit - maybe they're being nice to you. Most likely they're bored. Next 5 seconds their mind will be to something else. Plus, Facebook is ruthless to the freshness of things, so shit you spent a lot of time producing only gets a shot temporarily in the present and then imediatelly forgotten if they shared to 10 people and they don't care. You're not a creator, you're an easily replacacle cog in their system. I have had things that picked up long after I produced them on my site - I can't imagine doing that with Facebook.
That was inadvertantly a perfect way to describe the "info" people get from Facebook.
