Our results show that scientists who interacted more frequently with journalists had higher h-indices, as did scientists whose work was mentioned on Twitter. Interestingly, however, our data also showed an amplification effect. Furthermore, interactions with journalists had a significantly higher impact on h-index for those scientists who were also mentioned on the micro-blogging platform than for those who were not, suggesting that social media can further amplify the impact of more traditional outlets.
I’m surprised there’s no mention of altmetrics in this piece. Results are relevant for altmetrics, though. Hoping they’ve published the study in more detail somewhere so I can check it out.
In any case, this is a quick and thought-provoking read — though it appears that it’s more about being tweeted to the top than tweeting to the top (two are interestingly related, however, I suspect).
