I had created my Twitter (now X) account many years ago. When I first signed up, I tried using it for a few days but found the user experience to be vastly different from Facebook, so I stopped. The account was then left unused from the Twitter era until Musk bought Twitter and renamed it X. I actually never thought about using this social platform again. Until this year, as I started investing in US stocks and cryptocurrencies, I found discussions around these two areas to be quite lacking on Chinese social media platforms. In order to get first-hand information and insights from professional investors (whose thoughts and articles typically only appear in small amounts on traditional web news media), I gave Twitter (now X) another try. I was amazed at how useful it is. There are very active discussions about US stocks and cryptocurrencies, with new ideas being shared every hour. Some are just personal speculations without much value, but there are also well-illustrated rational analyses, which are exactly what I enjoy reading. Compared to Facebook, what I like more about X is that any reply under a post can become another main post itself, allowing further discussions under that reply. Truly valuable opinions, even if not the original post, can gain traction and become more popular than the original post due to the higher discussion value. When I realized this threaded discussion structure, I felt this is a better way to surface popular ideas. Other features like the ability to monetize good content are also mechanisms that I think can make the platform sustainable. Many people are incentivized to produce valuable posts, benefiting themselves as well as the platform - a positive cycle forming a mutually beneficial relationship with users. Even as a heavy lurker, I have been motivated to promote any new blog posts on the X platform going forward.
