Reference social media

We could potentially post new Open Work items to multiple targets, such as:

• Twitter, tagged with specific languages
• Slack, to specific language channels for instance
• LinkedIn, or some other data science ways of finding workers and targeting them
• Instagram/Pinterest potentially to hunt for web designers
• Google Advertising
• There may be scope for custom landing pages, campaigns, etc.
