There is also twinery or inklewriter for simple text stories with an online authoring option. And Inform7 for full on text adventures, where you write the stories in a declarative manner as plain english.

I like squiffy as well, though its not as popular or elegant. Possibly just nostalgia.

& Evennia is very cool if you want to make a multiplayer one!

One of these days I'll try out Inform7 it seems so cool but haven't had an idea for a game that could use it yet
