I used to use Yahoo Notes for this. When they shut it down I created my own web app for this, and now it is available to anyone: https://circles.app
Features: Notes can be accessed from any web browser. Web site is mobile friendly. You can share notes with others. You can encrypt notes. And the most important feature: You can download all your notes by clicking "Download all" and you get a .zip file with plain text files (with line breaks compatible with your OS).
Other features: You can save links to random websites, you can create lists, store some files and so on.
We are open to opensourcing Circles. What if anyone could start their own Facebook-equivalent site using opensource? What if we could splinter FB into 10,000 sites?
Absolutely. React started off simple but with things like Redux added on, it has become unnecessarily complex. The performance benefits of React is overrated. Javascript is so fast these days that you can rerender the whole page on navigation and no one will know the difference. I built a whole social network site based on a simpler alternative, UIBuilder, and you can see for yourself that it is performant: https://circles.app
This might be of interest to HN community: we didn’t use React, Angular or Vue. We used https://github.com/wisercoder/uibuilder and an MVC library. Both are simple, tiny libs each no more than 500 lines of code. We don’t get the point of large js frameworks. React is overrated.
