Topic
I haven't yet heard back from the search committee, and it's been a week/two weeks/a month/two months already and I'm really, really anxious and I think I should contact them. It will show that I'm still keen on the job, and all the interviewing advice says to follow up after the interview to show you're keen to take the job, and it will show initiative and gumption and I think I'll contact them and ask for an update.
Consensus
Don't contact the search committee. No, really. No matter how friendly they were and how many hints they gave you. If they're going to offer you the job they'll get in touch. The only possible exception is if you have a competing job offer in hand. Do you have a competing job offer? If not, don't contact them.
