Project Euler Forum

In the private threads for the problems, please add a "Post Reply" button to the top of each page. Currently one has to scroll all the way to the bottom to find this button.

Also, please allow for the sorting of posts in the threads by one's programming language.

As we try to make clear in the forum rules, posts are meant to be constructive and/or add something original to the thread. When a member solves a problem, the threads serve as a place to share different approaches and insights into the problem that has just been solved, adding to the learning experience of having just solved the problem in one particular way. Placing a "Post Reply" button at the top of the thread encourages members who have just solved a problem to post their code without taking the time to carefully read and learn from the posts that already exist. In most cases, we get repetition and the quality of the content in the thread is diluted. Similarly, the most valuable posts begin by discussing methods of approach and algorithms, before posting code. So filtering by language would most likely remove most of the most valuable posts. Whereas posting code is never discouraged, it is of far more value if a member can say, "I used the same approach as X, here is my implementation in Y." That could only happen if all of the existing posts had been read.

Fair points. However people who want to read every post (or sort by popularity) can still do so, while the people who are searching for a particular language have to scroll and search every post. If that's what they want to do I don't see a reason to force them to do it manually.
