In the past, I've been working on some products that launched and had some success.
From time to time I'm developing my ideas for my friends to use. Got feedback but I didn't scale for more users. Some projects have never seen the light.
Right now, I'm working at urlworker to improve it and attract users, not just my friends who are crawling websites from time to time.
My biggest concern is that I'm not that good at communicating and gathering users, but I'm betting on forums where I'm active. Got some users from Reddit.
One of the improvements I want to make is to create more info content for my project about what is it, how to use it, and some tutorials with use-cases.
I'm hoping that someday I will monetize it somehow. Until then, don't give up on your ideas, maybe one will succeed.
