I believe that spreading honest information(it may be good or bad) is really a huge thing to improve bitcoin community. It really is a big help especially for us newbies who are still learning the bitcoin world. I've read a lot of quality informations here that is giving great ideas, advices, and techniques if you're new and just starting.
In order for us to improve the bitcoin community I think unity is what we need. We have to figure out the ways to avoid hacking and stealing of account in bitcoin to make sure it's safety. Then to have a big number of bitcoin users and investors we should promote it in a good way wherein it's informative and can encourage others to join.
