Building things in public is the best route you can choose.

In the offline world, your products can't sell without your showroom.

Presenting your ideas in real form is the only option to get attention.

The same goes with Content, doesn't matter how well you study or research and put your words in sweet format.

If you are not posting online then you will not receive any attention and feedback.

Doesn't matter if you write effective code or creative content you should present it in the real world to get rewards.

I know many Shakespeare who are great writers but are afraid of posting their stuff online.
