People have ideas. Some are good. Some are bad. It is difficult to keep up with them, it is difficult to filter them and discover things. It is difficult to follow idea updates. It is difficult to describe ideas. It is difficult to get feedback on ideas.
Many ideas are never shared, or are shared to few people and forgotten even though they have potential to be further developed and grow. Also people have similar ideas but are not aware of each other projects. Ideas can be merged together, shaped and changed for the better. Teams can form. I propose to build a directory of project ideas to address these and other issues.
I am scouting interest and critique for this idea. I can build a prototype for it, but it needs feedback beforehand. If you are interest to critique or get involved a bit, please contact me.
TL;DR: If you think those are your users, probably talk to them. Can you describe a version of an EA directory of ideas that they would use right now?
Maybe even be concrete, draw it on a paper (or Google Doc) and ask them what they'd click. Don't be vague, like "imagine the ideas on the list were really good", put examples. Or if you don't have any, find a user that would add examples.
My prior is that there is a version of "EA directory of ideas" that would work really well, but I'm not sure what it is, and (especially in a project that has a network effect) I wouldn't assume that "if you build it they will come"
Again, just my priors, totally feel free to ignore
