I have had many ideas in the past. I started working on them with exceptional zeal in the beginning but that excitement starts to fade away soon enough when next "great" idea hits me.. In some cases When things actually get starting tough , i drift away. I have many such side incomplete projects which give me guilt trip every now and then.
I am sure you also have the same experience. I have pondered upon some reasons why this might happen:

1. Difficulty to find people to work with : Many people don't find idea that intriguing (this is ok )

2. Lack of Technological knowledge : Even if you find people interested in idea they don't have knowledge required to develop that idea

3. Lack of mentor ship : Even if you come up with any idea , it needs a lot of fine graining. You need to decide on functionalities , tech stack and many other things. Lack of mentorship takes its toll here

There are many other reasons (obviously) but i think these are top 3.

Would you be interested to use a platform which facilitates collaboration between people , helps you broadcast your ideas to larger audience and build a dedicated , talented team ?
