Reader's Digest 7月号にソーシャルネットワークについての記事がありました。その一部を引用します。
Here's the second secret of social media: everybody uses it for more or less the same reasons. Older generations often sign up to stay in touch with children, nieces, nephews and grandchildren.

"old-fogey" は前に "Older generations" とあるので、その世代の人間を示したいる様ですが辞書で確認します。
・Oxford English Dictionary: A person, typically an old one, who is considered to be old-fashioned or conservative in attitude or tastes: 'a bunch of old fogeys'
