I want to know if these sentences are not weird:
Democracy is government of, by and for the folks.
Within minutes of the event, folks were tweeting about it.
Many cafés and other public places now offer folks a wi-fi connection to the Internet.
In my view as a new English learner, the sentences I wrote up there are all weird (I can't tell the reason, I just sense it is). I'm intending to increase my vocabulary by studying all possible synonyms of a word that I can use exactly the same as the original word.
By the way, if you ask me where I got those sentences, I picked those words from my vocabulary exercise book,and just substituted the word people with folks (plural).
