Good day everyone, may the peace of the Almighty be on this community as a whole.
Some of the ways creativity can be encouraged is setting up more contest, games, and platforms like @pobtalk and @pobstreet. It will really help alot, people get to brainstorm, talk about a situation deeply and get it solved, the platform has to be interesting. However, each other problems can be halved solved if not totally solved, this depends on how cooperative, friendly and how much we trust each other; If this is done, the community will be no doubt interesting, more people to dive in, because the real conversation exist here .
Above all, I think effort should be rewarded(with up votes) not only success, this will really go a long way, it will eliminate the act of given up.
