I have been on Twitter for awhile now.  I've wanted to write a blog post about it, but my thoughts range so much that I thought I would share some random musings:

1. There is no sense of permanence or posterity.  There is also little sense of who has read my tweets.  This can make it feel like I am a crazy man wandering a city street.
2. It's much less trite than I thought.  Often people share good information and offer profound insights.  I'm much less anti-sound-byte than I used to be.
3. At times it can feel like chaos in a crowded room (it's why I probably won't be back to #edchat) and other times it can feel like a tiny circle having a conversation.  This erasure of space, this fine line between synchronous and asynchronous communication can feel dizzying to me.
4. I can never predict what will go viral.  I know that short, provocative statements sometimes become popular (often unintentionally).  For example, I had tons of retweets with the question, "Why are we bailing out failing schools and propping up failing banks?"  It was a line from a previous blog post, but I ended up having around seventy people retweet it. 
5. Unlike blogs, Twitter feels much more collective in nature.  There is more geographical heterogeneity, but it is much more homogeneous ideologically.  Nearly everyone seems incredibly pro-technology, for example.
