With over 10k visits, Why only 15 new users created content on our platform?

We are building a product https://tymline.co/ (timeline based story blogging platform). Here, people create timelines to narrate stories of any kind like relationship, career, travel, hobbies etc as timelines which can be discovered basing on users interest.

We have been getting decent referral traffic to our platform but only 15 new people have created timelines organically. Others either read a story or check the platform and drop off.

Sample timeline: https://tymline.co/SiddharthRam/siliconvalley?ref=hn

1. How to make the content creation more easy through timelines?

Any suggestions or feedback to improve the product would be helpful for us to iterate further.

TIA
