I have used the Lanka software foundation website for open-source software development, and overall, it was a satisfactory experience. The website provides necessary information and resources to get started with open-source development. However, the design feels a bit outdated, and there is room for improvement in terms of user experience. The documentation could be more comprehensive, especially for beginners. Despite these minor drawbacks, it's still a decent platform to contribute to the open-source community.
