I said this one would be about Tweeting at events, it morphed a little to put it mildly. I have split it into two parts which means I can keep this one brief:
I will Tweet before an event, to raise profile and rally a community.
I will Tweet after an event to cement connections and make secondary introductions.
I used to Tweet at events a lot. Now I am very selective, it can be very powerful and enable me to connect with others and allow those not present to be involved also, but less is more.
First and foremost I am trying to enjoy where I am, what I am doing and who I am with, using the technology selectively and with deliberate purpose.
