Assessing Impact

ResearchBlogging.org and PLoS are teaming up to improve how the impact of journal articles is determined. PLoS began its metrics project earlier in the year and now part of that metrics tab for each article, readers can see, in addition to how many people have viewed and commented on the article, blog posts about it from the ResearchBlogging network. "Since the site carefully vets every blog and rejects both blogs and individual posts that don’t meet its guidelines, these posts represent the best commentary the internet has to offer about peer-reviewed research, often from experts in the field," writes Dave Munger at ResearchBlogging.org News.
