According to Wikipedia (http://en.wikipedia.org/wiki/H-index) “the h-index is an index that attempts to measure both the productivity and impact of the published work of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications.” If you quickly scan the average number of citations per scientific journal article, you are likely to see a range of 5 to 10. Because a few papers are cited hundreds or thousands of times, there are many papers on the other end of the distribution that are never cited.
Using myself as an example, my most cited publication has accumulated 81 citations over the past decade, while 7 of my papers have never been cited. In contrast, over the past six months, I have made 7 presentations that reached 850 individuals. Recognizing that the h-index does not reflect the total number of individuals who have actually read a paper, but rather just those who cited a paper, this isn’t really a fair comparison. However, giving presentations is an excellent opportunity to enlighten an interested audience about your research.
