Facebook is a nightmare, it's built around the concept of spam but since all your friends are on it, you have to be on it. Every app tries to force you to click on things you don't want, so that they will end up in your news feed and attract more sheep. Every few months, they add a new concept that raises tons of questions about privacy and yet their default settings is almost always to allow every user into the new thing (think auto-tagging via facial recognition). The best part of all? They don't even tell you there's a new feature and that YOUR PERSONAL privacy settings have been set to "allow all" for that new feature.
I have been waiting for something like G+ to kick facebook in the face for so long, now I only need an invite!
Google+ is coming to late to a party
that started years ago
I'm also not sure what problem Facebook (or social networks) solve, that email, your IM account and your phone with its contacts list do not.
Where I live most Internet users are also users of Yahoo's IM. I've been reading the status messages of my friends, interacted with them, getting back in touch and all that - for years before Facebook became popular. Yahoo's IM is still the most popular form of communication between my friends, although all of them are also on Facebook.
My current IM account is 11 years old, my mobile phone number 10 years old, my email account is newer since I migrated to my own domain and my name is searchable on Google -- every one of my acquaintances I ever had know how to get in touch with me and do so.
And that's Facebook's flaw; Facebook was once cool, now it is getting more popular because it is popular; but a good communication medium it ain't
I know that Facebook Messages can be targeted to groups, but they aren't really the same thing. Messages aren't designed for sharing; they're designed for, well, messages.
Facebook works. All their friends exist on it - it does everything they could possibly want it to do "connect to their friends". In my mind - it's "Google and Bing" all over. Bing works and is arguably just as good as Google these days yet everyone continues to use Google.
Google+ - great for technology people who want to "control their data". Most of my friends don't even understand what "exporting data for portability" even means. They use Facebook, see their friends posts, upload photos, check-in to places and they love that.
It's going to take a LOT MORE "innovation" to move them across to another platform because "it's new, pretty and contains some nifty features that Facebook already contains or will contain in the next 3 months of 'lock-down' in response to Google+". I'm not on Google+ [outrageous request for invite via my profile :D] - but I just can't see my friends moving to it - particularly when they don't even login to Google anyway when they are searching.
Facebook will "win" in my mind - because they are agnostic to email and that's where your "connections" lie and the reason you use Google "mostly" [outrageous generalization again] is because you host your email on Gmail.
Facebook makes that process tedious. Google+ bakes it in to the foundations and at every step in an obvious way.
@1. you can do that on Facebook, too ... they even have "circles" there, too
@2. facebook is the champion of playing nice with other sites, just look around you ... everything is facebook nowadays
@3. facebook borrowed a lot and you can filter everything everywhere.
So maybe their UI isn't as clean as Google+ and they lack a great video chat, but other than that, why should anyone switch to yet another social network which does the same ... once was enough for many people, now that everyone and their dog is on the leading network there is no incentive to switch away.
Google+ is coming to late to a party that started years ago and will suffer the same fate as other Google products: only geeks will use them, no matter how good they are (Wave :/) ...
