ALTMETRICS
altmetrics is the creation and study of new metrics based on the Social Web for analyzing, and informing scholarship.

QUESTIONS
• How do we know whether this measures true academic impact? • What sorts of new filters are necessary?• What kind of impact are we measuring?• At what level of aggregation (if any) are these metrics useful for?• Can we gain analysis by going for scale?• Can science maps help us overcome variance in our datasets?• How do we determine what population we are talking about?•….

CONCLUSION: WE ARE JUST STARTING
Reminder:
“It took approximately a generation (20 years) for bibliographic citation analysis to achieve acceptability as a measure of academic impact." (Vaughan and Shaw, 2003).
