Congrats on your recent press release, "York librarian validates social media metrics for research impact evaluation," getting a lot of attention on Twitter! Altmetrics is an exciting and fast-growing research front, and it's great to see Dr. Li and York University pushing this research forward.

However, I wanted to let you know that there's a rather significant error in the piece, which claims that Li is "the first researcher to ever have a study validating the usefulness of altmetrics published in an academic journal." This is really quite incorrect; in 2011, multiple peer-reviewed studies [1, 2, 3] reported correlations between altmetrics and citations, or predicted citations using altmetrics.

Of course, this error isn't intentional, and I'm sure it'll be quickly corrected. Since researchers get pretty intense about who gets credit for primacy in a given space ( ask Liebnitz :), I'd encourage you to carefully fact-check these kinds of claims in the future. In the meantime, I'll post a copy of this email online to inform folks while you work on the correction. Thanks, and congrats again to York and Dr. Li for the great work.
