This kind of sounds worse than what I hoped for, but I am happy that after 20 years project exists and advances. Everyone who was taking part deserves more than a piece of cake for sure
I think this kind of roadmap and release cycles might put some people off from contributing, but this is why BeOS>OpenBeOS>Haiku history and community needs to be documented in a popular way so people can get a feeling for it (beyond harsh metrics).
Maybe a media-rich wiki project would be nice to have so everyone can contribute, work in parallel and also show different levels of complexity in such project and community. I would commit to both brainstorm, co-develop and contribute to such thing (anyway busy with wikis and media). I used to do this on BeBits wiki (which I kind of asked for and loved :-)…
Is there any wiki in use these days for any purpose similar?
