Continuing the discussion from here and here, let's keep this as a master list of suggestions.

Find places where economics experts post, and post links from there to context-relevant Q&A here. So if we've got a good Q&A on a particular market failure, and that comes up in discussion somewhere, then post a link there back to the Q&A here. Use the "share" link under a question or answer to post a link that's unique to you: that way, you can earn bronze, silver and gold badges for pulling in traffic. Don't spam: just share our quality content in a sensitive, thoughtful and helpful way.
And it can often help avoid misunderstandings, when linking to content here, to mention that we're not a forum, we're a Q&A site, and so we work differently to forums.
