Is Facebook still such a big thing to people? There was a time when everyone and their dog were asking "are you on Facebook?" with eagerness and then looking at your as if you had publicly fluctuated when you said "no". With over 271 million domains on the Internet, it seemed odd that people were going crazy over one or two (Facebook and Twitter).

But now people just accept that you don't have an account and are happy with emails or face to face communication, whether that be in person or via conferencing of some form.

If social networks were relevant to everyone, then I could understand you saying that Google was in decline. However, they're not important to everyone - they might be in your circle though. Finding things on the Internet is still pretty big though, as is email.
