Every site needs to be able to promote itself to people who will be interested in the content of the site. In fact, promoting sites is one of the The 7 Essential Meta Questions of Every Beta. So here we go!
Everyone thinking about this should read: A Recipe to Promote your Site. That blog post has a lot of good, basic information about promoting a site. But that link also encourages innovation. That's what this post is for.
Please post an idea for promoting the site in a community-wiki answer below. Each idea can be discussed using comments below the question (chat is also a good place to discuss these things.)
Note: This post is for general ideas for promoting the website, likely we will have other questions on meta about promoting.
But, how do you go above and beyond simply sharing links to great questions? Get specific! Rather than asking giant, hard to answer big picture questions like “How do we promote our site?”, start by asking bite-size, specific questions that are easier to answer — more along the lines of:
“What are the three biggest webmaster conferences we can sponsor?” “Can the GIS community support a ‘Dev Days’ like Stack Overflow?” “What are the top 10 photography podcasts that might pick up on our site?” And don’t stop there. When you get your first round of answers, use those answers to get even more specific.
“Does anybody know photographer Scott Bourne (http://photofocus.com/) to ask about talking to us on his podcast or to his Twitter followers?” This takes a bit more coordination and discipline than asking a one-shot question and expecting a final solution to simply emerge. It takes individual members to rise up and ask methodical, step-wise questions with an end-goal in mind — and follow through.
If you have questions about an idea that wouldn't fit in comments, or want to get something more attention than just through comments, you can ask a specific question about promotion.
