I think you are pulling the plug too early. You just finished the development part. Now is time for marketing. Believe it or not, just posting on hackers news have gotten you a few new users. (maybe it was your plan all along ) But still now that you have refined the code focus on the users listen to their needs. And focus on acquiring more. The game only begins. 49webzone.com was started by a friend of mine and it took off only after 13 years.

I just deployed my first big project last week and my plan is to spend 80% of my time on marketing and the rest on fixing bugs. Maybe it will fail but I will make sure I do what most of us developers try to avoid like a disease.... Marketing!
