Some good community projects:
steemstem
curie
utopianio
...
Something that could be cool to do is if you took a small percentage (say 5%) of buildawhales VP and handed it over to the curie crowd or something like that (so 5% means a 100% upvote would use 10.020.05) as it would help out the project and those that get support from it.
I pay to lease the SP so it isn’t something I can do at this time.
