I'm been working on providing a service to recommend manga. The only other existing alternatives are myanimelist and mangaupdates and I feel my project has a greater potential to be more comprehensive, up to date, and personalized.
There's definitely been some changes since then, so a third writeup is in the works. I know this project isn't very polished or professional, but it's something that I've wanted to work on for a long time and I feel that it solves a very niche problem in an interesting way.
