The one good thing about the word is that the alternative is ubiquitousness, which is obviously ridiculous as ubiquitousness tastes of the orange sheen of street lamps on wet tarmac that has millions of mosquitoes squashed into it.
Ubiquity is to do with existing everywhere, and one other good thing about the word is that, people having on the whole fairly good taste, ubiquitous isn't anything like ubiquitous.
And thank heavens for that.
Word Not To Use Today: ubiquity. This word comes from the Latin ubīque, which means everywhere.
