Altmetric measurements derived from the social web are increasingly advocated and used as early indicators of article impact and usefulness. Nevertheless, there is a lack of systematic scientific evidence that altmetrics are valid proxies of either impact or utility although a few case studies have reported medium correlations between specific altmetrics and citation rates for individual journals or fields. Finally, the coverage of all the altmetrics except for Twitter seems to be low and so it is not clear if they are prevalent enough to be useful in practice.
In this post I want to pull together a couple of ideas around some of the measurable user activity generated as part of CFHE12. This will mainly focus around Twitter with some data from blog posts. I conclude that there are some simple opportunities to incorporate data from twitter into other channels, for example, summary of questions and retweets.
