I would also add that there are a few different types of power users. Two off the top of my head are "very active users" and "very technical users". The foremost often can be maintainers of communities. Example: Reddit or Discord. These same communities might end up being the main part of your product. Other examples include social media like Youtube, or even Instagram. To these users a different set of power tools are needed, than for the "technical power users" who need different kinds of power tools. For the "very active users", you might want to be able to provide things like UI customization, social media linking, statistics and easy tools for moderation. Examples of tools for "technical power users" might be providing a large set of actions that can be custom-key-bound. A macro/scripting API. An alternate API to your service completely (REST-ful), or support for modding. You can guess what those tools will later be used for quite simply I'm sure. :)
