Zuckerberg is what I might refer to as "forced" network effects. And I don't mean the natural network effects that result from people using a good and hence popular product (or network effects building on itself). Facebook replaced people's emails in their profiles with fb.com addresses, the company lied to people about privacy forever but especially with the former it's the site that actively tries to take you over. I despise Google, but Gmail wasn't like this (and supposedly Facebook would actively delete posts linking to its competition, in the early days - and maybe not so early days)

My point in this somewhat rambly post is it's always been a spammy mess and Zuck's never had an interest in making a good product. For him it's literally about domination

And PS: yeah, I know. With Chrome Google is apparently trying to dictate standards in a similarly cynical way
