As the steem developer list is growing fast here is an update with plenty more devs and their projects.

As before feel free to share your projects, other devs you know or report wrong information in the list.
And if you want to help me a bit create a PR with your updates on github.
ps: I know that the markdown table doesn't look great sometimes, e.g. on mobile or ChainBB 
pps: If you're on the list and don't want to be @ mentioned for updates, let me know..
Steem on..
