You can look at dialect, we have become more global in the last decade than ever b4...

People have become more politically correct.

We all use words that over do it. I think that over the past 10 decades, we have become more intelligent (technology, but also simplified parts of our spoken language) LOL, BFFF, etc... Dude rather than gentleman

Answer 2

This site gives some very technical analyses in changes in grammar: http://www.comp.lancs.ac.uk/ucrel/floblob.html
(To summarize, less use of the passive voice, more use of the present progressive, for example: "I am loving it." instead of "I love it." There is also a shift in usage of modals--a decline in "must" "may" "shall" and an increase in "have to" going to".

This site discusses "California English" :http://en.wikipedia.org/wiki/California_English. Basically there are two aspects of California English that represent shifts in the language: 1. Pronounciation of vowels and 2. Diverse additions in voabulary, phrases, and slang.

The media as well tends to standardize grammar and pronouciation while introducing new terminology into common speech. This article discusses this issue in quite a bit of detailhttp://muse.jhu.edu/journals/american_speech/v075/75.1fitzmaurice.pdf#search=%22recent%20shifts%20in%20spoken%20english%22:
