well let's be honest.
thisyear and lastyear sounds like a pretty bad screenname.
nextyear. sounds good

add to that the intentional misspelling-> nxtyear. beautiful!
if you want the honest reason why i'm nxtyear,
i was listening to the Foo fighters song Next Year while i created a new account somewhere.
so i was gonna use Nextyear, but i mistyped it as nxtyear. and so i became nxtyear.
