I think you have it wrong. Regardless of the positivity you received when contacting the recruiter, he or she may have 100 applications to deal with at the moment, or a workload of their own, such as staff meetings, etc.
It's totally up to you to show you're the best person they can hire for the job. There are no expectations you can have on the recruiter, his or her expectations are from his or her management to fill the vacant or newly opened position.
It really is up to you to show interest - give the recruiter a day or two at the most, then follow-up and just remind him or her of who you are and your conversation the other day. Recruiters are human.
Good luck in finding a new position for you to grow, and befriend new colleagues! :)
