I signed up for a Twitter account back in 2009, but never really understood the point of it.
Recently (the last few years) though I start to appreciate it more, as more and more professionals, scientists, engineers, politicians, journalists, companies, whistle-blowers, developers, startups, entrepreneurs, freelancers, celebrities, influencers etc, use it to build their personal brand, and connect with people around the world. They are also collecting and utilizing increasingly more, and more important, real-time data.
As of late I see some positive improvement to their business:
(1) Better ad-targeting (perhaps due to better machine learning algorithm).
(2) Better user engagement (

Interestingly, in certain countries (like Japan), Twitter usage has exceeded Facebook.
(3) Also, better profitability, and better balance sheet.
That said, as a business, I don't understand their long-term goal/story; hence, still sitting on the sidelines. Twitter investors, especially those that initiated position after Dorsey returned in late 2015, during the lows of 2016 - 2017, should be quite satisfied with their returns, as well as improvements in it's business fundamentals.
