If project is having potential..
You dont need to build community...
Community will automatically rise...
Sounds simple but this line do really got that point!
If the project do really have that innovative or simply do have that potential behind.Community would be the one who will follow and support
that project until it do create some buzz either if the project owner itself would tend to showcase it off on the initial phase or just simply
decide to keep it silent because if exposure isnt the intention on the early phase then it do get some recognition gradually then it signifies
on how good it is.Community building would gradually arise.
