Having your work formally cited by other researchers is a very slow process. Altmetrics (number of tweets, blog posts, likes, bookmarks, etc. in social media) are faster and wider-ranging measures of how people—both other researchers and the general public—are interested in your work.
ImpactStory is a free tool that brings together a diverse assortment of altmetrics and traditional citation metrics for your research outputs, including both journal articles and datasets. Run a report on a particular journal article or dataset using its DOI or PubMed ID, or import your entire bibliography of articles/datasets using your ORCID (Open Researcher and Contributor ID) or a BibTeX file exported from Google Scholar.
In Faculty of 1000 Prime, expert scientists and clinical researchers hand-pick interesting articles, rate them, and comment on their importance.
