I had an idea that I started working on. I found out there was a similar website doing the same thing and I liked their implementation. At the time I thought it was smart and thought "why didn't I think to do it like that?". After being disheartened, I scrapped the idea and went on to think about other things/problems.

I haven't come across that site or that idea in other sites since which leads me to believe that it didn't take off. I can't remember the name of the site either. This either tells me that the idea was flawed or their execution was poor.

Since I (still) like the idea, I logically think that their execution must have been poor. I'll probably start working on my version again soon. Unfortunately that was a lot of time wasted. If I had continued back then instead of stopping, I could have a successful product by now (or not, of course!)

I'm not sure if this comment will help you decide to continue or not but in my opinion is that you should. If it doesn't work out you will have learnt a lot anyway.

Good luck!
