By putting myself 'out there' I am opening myself to the contribution that a wider network can offer me.
It is a reciprocal thing, I read many blogs and feel connected to the thinking and experiences of teachers who are way beyond my local geography. Many challenge me, inspire me as well as inform me. When I can, I connect, I might comment, tweet or share on Google+ within my school community.
A blog post published and sitting there might as well be in a written journal unless we share it. I use Twitter and through that get an audience to my direct learning network and beyond by means of retweets etc.
A recent post was linked to a few other sharing sites around the world and my simple story about getting students to write blog comments was viewed by more than 200 people in 24 hours. I honestly thought I was simply annotating some ideas for myself - some resources for getting students to interact professionally online - but apparently it was if interest to others.
