Easy Come Easy Go
I just read that a lot of the social news reader traffic publishers like Washington Post and The Guardian were getting from Facebook has dropped off dramatically.
Next we will read that the traffic social video apps get from Facebook has dropped dramatically.
All of this reminds me of the big drop in traffic SEO driven sites deal with every time Google does an algorithm change.
SEO and Facebook timeline integration is "best practice" on the Internet. You should do both. They can be great free acquisition channels. But they are not great retention channels. Because easy come easy go.
Be your own bitch.
