Here's my full idea - based on an activity I saw with @mountainwashere and @steemstem -

Users with facebook or gmail login submit pictures of unidentified plants and animals along with relevant information (location, climate, time of year, etc) into a website, which publishes IDENTIFICATION CHALLENGE on steem and uses steem power to reward the experts who help identify the species.

Users are informed through google or facebook once their submission is identified.

This is just the use case that I have thought of - when you start thinking that there is not enough SP for everyone on reddit to have one, other ideas start occuring to me. Also free account creation has been slow recently.
