I actually started this because I wanted to track my own applications but also wanted to solve the problem of making the process more transparent for applicants. Just like the "static HTML" part, a 2 weeks rule is a general guideline, but surely we can do better than that. Especially when there is no recruiters' contact after applying, going beyond a simple yes/no answer by providing community-driven data (historic and current) would help a lot (as seen in the links I cited). Thanks again for the insights!
