Dictionary words mean different things to different people.
Timid is a great word to own but how would you sell it, develop it or monetize it? There is a rapper named Timid The Official Website of Timid - No Time For The Jibba Jabba but how good can he be if he is timid in his rapping style? Timid- lacking in courage or self-confidence. Perhaps you can monetize the name by developing a site that offers self help books and information on how to become less timid.
I like Falter much better. There are several sites that have the name falter in them, it is also a surname. As a dot us extension you could also develop it in a political sense...to hesitate or waver in action, purpose, intent, etc.; give way. You could give examples of any president faltering in their promised actions.
