I guess I will have to start first. Do you want to talk about Facebook and posting in groups on Facebook in a way that is not seen as spamming?
I’ve been experimenting with different strategies and I can share my experience. Good moment for sharing your domain name for sale is in the process of creating a logo for instance.
I will give you an example with my name RedPair(.)com. When the name was approved for premium couple of weeks ago, I posted a question in a Facebook group called something like “What does it mean?”
I asked “What can be red and goes in pairs?”. I received lots of suggestions and I involved in the discussion. At some point people started asking why did I need that, and only then I explained that I needed it for a logo for my name. Nobody saw what I did as spamming their group.
When the logo was ready I shared it with the people in the group. They felt like they were part of the process with their ideas. It was a common achievement.
