I haven't participated in any challenges, nor do I really want to. Some of them might be kinda interesting, but I just don't really want to spend the time on them. Maybe if it was somehow more relevant (eg, giving you rep instead of just a badge), but even then I wouldn't be particularly interested. Also, I'm just not active on Stack Overflow at all.

> We would also like to know if there are specific types of challenges that users want to see. Are there certain topics, modalities, or technologies that you would like to see a challenge on?

Assuming this is referring to SO challenges, not particularly.

> For users of sites other than Stack Overflow, could some version of challenges work on your site? The implementation could be different (especially if it's a non-technical site), but do you think your community would enjoy some friendly competition? What would make it successful, interesting, and fun?

I feel like maybe the only other sites where Challenges might fit are Puzzling and Codegolf. Except... Challenges are basically there anyway. The questions that get asked there aren't really asking for the answer to a question, per se, but instead what the (optimised) solution to something is. That is to say, Challenges wouldn't really bring anything new. That's not to say that their respective communities wouldn't like it (they might very well want Challenges), but there's not much of a "point", for lack of a better word.

For non-technical sites, there may be something, but I struggle to see exactly what. I feel like Challenges just wouldn't fit for the majority of sites.

All that said... I don't really care about Challenges. I imagine most users would agree with me. Personally, I would *much* prefer if resources were allocated to long-standing feature requests instead.
