Datamining stackoverflow to provide some interesting statistics.
TL;DR version at the bottom of the post
- Number of coders drops significantly with age. Top developer numbers, at age 27, drop by half every 6-7 years.
- Developers in their 40s answer roughly twice as much and ask half the questions compared to colleagues in their 20s. It seems younger generation learns and older generation teaches.
- Quality of posts, i.e. upvotes earned by post, only slightly increases with age.
- Seniors earn their high reputation by being more active than younger developers.
