Irrelevant. Users sign into FB, there's a pale yellow thing at the top saying "You don't appear to be using the FB browser, click here to download it for X features that make your life easier".
That'll vastly increase that 2% - almost a billion people use FB, that's more than 1/6 of the entire world.
The amount shared on Facebook is doubling
every year.
Of course their growth is slowing down a bit though, there's only so many people using the internet, and only a certain proportion of those are ever going to be open to social networking.
FB growth is slowing down because the market itself is not expanding fast enough. (i.e. total number of internet users). Its primary market is people aged 18-35. There's only so many people with internet access in that demographic. They have
1 in 6 of every damn person in the world in their database.
You're just plain wrong on this, and clearly completely detached from Facebook's core demographic.
Anyone that quotes Myspace, or talks about decline or whatever else clearly isn't an avid user of Facebook, or see's what's going on. Every year I see more being shared on Facebook. Of those I went to school with, there's not a single person I'd want to communicate with, that I can't communicate with via Facebook and get a reply within a day, perhaps 2 max.
That kind of engagement is unprecedented by any previous web company. It's not going to disappear over night, and I'm yet to witness any decline.
We're seeing a stage of the net where things start to merge together, a consolidation phase as such. There'll be new and interesting start-ups still, but they'll focus on tackling new problems.
Whilst crude illustrates how all the big social networks are different. Pinterest for example isn't a competitor, but it's a new thing that people are using
in addition to other social networks.
Another social network akin to Facebook will not overthrow them, unless they royally cock up (massive law suits, country-wide bans, that kinda crap). The massive network Facebook has in place is just too big to hope to compete with.
