a 'thank you' note, a generic one means nothing... but a follow up is a very good idea, if you can convey you are excited about the job. (but you have to be excited about /that/ job for some reason; not excited about a job in general.)
I mean, a follow up until you get a firm 'no' is standard in most sales, and make no mistake about it, interviewing for a job is sales.
