Honestly, we're not doing a great job of user acquisition right now, which is exciting because it means that 100 users/month is just the tip of the iceberg. When we started we spent ~$3,000/month on AdWords to get our initial customer base. Once we had enough users, we stopped advertising and word of mouth took over. We basically don't do any marketing right now, but that we're going to change that soon.
