At this point I think it's okay to include all of the above with an awareness of my audience in each of the outputs I use. Facebook is mostly family and friends from high school, college, and my kids' friends' parents. I don't need to link my blog posts or educational technology musings there. Twitter is mostly my academic/teacher comrades and groups, so I can post links to blog posts and retweet from my incoming base if information. Google+ is my cohort traveling along this same journey, so I won't post personal 'stuff' there like I would on Facebook. My blog followers are....well....do I have any? Hmmm. What do they want to read about?
The Gliffy I put together looks as all-over-the-place as I feel right now about my Personal Learning Network. I have a lot more inputs and outputs than I had on July 1 of this year. The ITDML program added so many new contacts, ideas, groups, feeds and resources to my already existing, albeit narrow, PLN. I am finding that I am contributing more within my PLN and curating information as I continue to sift through it.
As I continue to create and curate my digital identity, I wonder if the arrows will calm themselves down a bit. Perhaps I will streamline the method of input/output so my time isn't split between so many sources and individual social networking tools. Robert Scoble mentioned the creation of Twitter lists and using Flipboard to build and vet the inbound content one chooses - I think investigating those would be a worthwhile next step.
