Facebook is massive in scale and scope. Twitter is a public communication forum, but if I'm following you, you're not necessarily following me. LinkedIn is, simply, a professional network.
Putting a photo into your LinkedIn stream increases engagement up to 90%.
LinkedIn is very good for browsing relationships and hooking into your contacts' networks. It re-connected me with high-level execs I hadn't talked to for some time, who then helped me close various deals.
1 out of every 3 professionals on the planet is on LinkedIn.
Linkedin is for people you know. Facebook is for people you used to know. Twitter is for people you want to know.
The population of earth has reached 7 billion people, every single one of whom send you irritating emails to join something called "LinkedIn. "
I avoid Facebook, LinkedIn and Twitter, and if I need to communicate with someone, I email direct.
Social cohesion was built into language long before Facebook and LinkedIn and Twitter - we're tribal by nature. Tribes today aren't the same as tribes thousand of years ago: It isn't just religious tribes or ethnic tribes now: It's sports fans, it's communities, it's geography.
Social networks do best when they tap into one of the seven deadly sins. Facebook is ego. Zynga is sloth. LinkedIn is greed.
I am a huge consumer of social networks, and I utilize Twitter, Facebook, and LinkedIn. I'm interested and am learning more about Tumblr and other visually dominant sites.
