Using these will simply make you look foolish
1 Cluster: This term was used between the late 1990s and early 2000s. It lives on only in public sector press releases.
2 Hub: Like "cluster", "hubs" became a busted flush around seven years ago. Even county councillors rarely use it anymore.
3 Innovation: It's hard to believe that this was once an actual English word that meant something. Today, it is purely a linguistic prop, devoid of any actual meaning.
4 2.0: 'Web 2.0' is now a historical term, denoting a period of time (from about 2003 to 2006). It does not mean a new iteration of something.
5 Cloud computing: This was always weak: insert 'internet' for 'cloud' in any example and it means the same thing. 'Cloud computing' is now generally referred to as 'the cloud' (an equally silly term).
6 World wide web: Just as most websites do not require you to type the letters "www" anymore, the "world wide web" is now a tautology. (Everyone knows that the web is global.)
7 Cyber: The term "cyber" waned at around the same time as Keanu Reeves' career. It is generally only used by elderly news bulletin scriptwriters and primary school teachers.
