As someone who occasionally blogs and tweets about what I had for breakfast, I could take offense at Craig Underwood's, post title, I really don’t care what you had for breakfast - how social sub-network tagging can end irrelevance on Facebook, Twitter, etc. But I don't as the post is on target with some excellent points and good suggestions. At least I usually include pictures and the web site and other details about the place I ate (e.g., Photos of Breakfast at Square One in Los Angeles).
As Craig writes, relevance is subjective. Some people come to this blog because of the food, arts, music, and other stuff I write about on the weekend, others for the enterprise 2.0, Web 2.0, etc. stuff I write about during the week. A few might even come for both. But I am probably the only one who is interested in all the stuff I cover. Actually, that is good as I also use this site as a personal knowledge management system. I am starting to do that with Twitter also to save links with context, but what about the rest of you do not want it all? Perhaps I should be like the New York Times and offer the weekender subscription.
Craig offers some useful suggestions starting with the concept of social sub-networks and social sub-network tagging. Of course tags are not new, but more could be done with them. We need to be more creative here and allow for more receiver control as Craig suggests. We need to work on the intersection of writer, tags, and reader. I cannot subscribe to particular categories of a blog or particular hash tags of a Twitterer. Of course, I can browse a blog’s categories or search twitter hash tags. But this is only a start. See Craig's post for more good ideas.
