STFU is not terrible advice if you don't feel you have a good mental filter for the things that you say and write. But offering advice and sharing knowledge doesn't necessarily have to be the same as giving away your secret sauce in my opinion. I release a lot of open source tools that we use but that doesn't mean I have to write blog posts about all of our internal numbers, strategies and future roadmap. You can share in even more generic ways such as business strategies in general, without going into great deal about your particular path. I think it's easily possible to share and be a part of the development/business community, yet still maintain your competitive edge.
