I have a personal side project (startup-ish) which I work on for almost a year now(maybe a few months less). The project is not monetized, as I try to build kind of a brand first. I have already spent around $3000 and there is just me working on it. I only have 500 sign ups so far, around 3k twitter followers (~90% are real) and the page views are very low.
Here is the screen shot from Google Analytics. http://i57.tinypic.com/59y9dz.png
As you can see, there are a few spikes. They happen from time to time when I work really hard. 2-3 days per month page views may reach to 20k visits a day. But then, the next day, the traffic goes all the way down to 400-500 visits. Today, there were something like 10k page views, but only 4 sign ups! I feel crushed and not sure if its worth to keep the project going. Do you have any advice? What should I do?
p.s. of course, I'm using a throw-away account for this question.
