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.
To be honest, I think that the best project in this space would simply be a newsletter. I think it could be valuable if a single person with good judgement followed a huge number of different EA channels to see what ideas people were posting and what stages various projects were in/what assistance they needed.
Of course, it would be important to check with people running a project whether they would be ready for drafts to be shared with a wider audience as I personally know that I wouldn't want my own ideas shared too widely before they were ready.
Personally, I wouldn't want to hear every idea that someone has randomly thought up or added to the directory, but only a curated selection. So if I had to choose one I'd take curation over personalisation. But it may be possible to do both.
