If your content resides at different locations, then the conversation can happen at different locations. If you post something on your blog and then link to it from Twitter and Facebook, there are already three places that the conversation can take place. And two of them are not actually controlled by you.
I solve that ‘problem’ by only posting here. No links to my stuff on social media, unless posted there by someone else. You don’t need to be a part of those networks to be able to follow the conversation. You can do that right here.
Wanna talk about what you read on my blog? Either comment here or write something in response on your own blog and let me know.
