So I released my app (http://www.ikeepm.com) about 3 months ago. I worked on it here and there when I had time. Yesterday, my phone kept vibrating to indicate new emails. To my amazement, I had 200+ signups in less than half an hour. At first I thought it was a spambot but Apache's log files showed otherwise. I'm now over 1000 users in less than 24 hours and it feels great.
Granted, the app is still free but at least people know about it. If I can convert 20% of those people to paying clients, I would be VERY happy. Anyways, for those who found "success" overnight via a blog article, how did you capitalize on it? I'm working my butt off to implement some of the new features people are asking for. Being a one man show means I'm limited to time at the moment.
