Gadfly definition from Wikipedia:
"Gadfly" is a term for people who upset the status quo by posing upsetting or novel questions, or attempt to stimulate innovation by proving an irritant.
So it was with some amusement I read this morning, on my email digest of Friendfeed, that the social media set look like they are preparing to flutter off to a New new service -
Rejaw. (Does the gadfly lay its young's eggs in the old host like some wasps do, one wonders

)
You can hear the buzz from the wings as they start up..... I wonder if any Dig-Anthropologists are studying the Dance of the Gadfly when it discovers a New Shiny Thing ?
No doubt an irritant to the Friendfeed crew, who have been luxuriating in Gadfly pollination the last few months after Twitter was no longer the nectar of choice.
