to estimate this might be to use capture - recapture methods. The simplest version is the kind used by ecologists. They mark some catches, drop them back in the lake, and then fish at random to see how many tagged fish they catch. They use this to estimate the number of fish in the lake. What you need to do this is two independent sources of information. Sample the first list (e.g., Technorati) and "mark" the science blogs. Then sample the second list (e.g., Google blogs or blogpulse) to see how many of the marked blogs are "recaptured." By looking at the number caught in both samples (recaptures) compared to the ones caught in a single sample, you estimate (by various methods) the number not caught in either sample (i.e., the total population). <a href="http://www.pitt.edu/~yuc2/cr/main.htm">Here's a link</a> that describes some of the models. </p> <p>I'm not a capture recapture expert so maybe someone else has an easy way to do this for science blogs.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2062657&amp;1=default&amp;2=en&amp;3=" token="O1P5hWasAW5f7AO9Wqf_dRBoBLhntNjaDUYHBm2mDcU"></drupal-render-placeholder> </div> <footer> <em>By <a title="View user profile." href="/author/revere" lang="" about="/author/revere" typeof="schema:Person" property="schema:name" datatype="">revere</a> on 17 Sep 2008 <a href="https://scienceblogs.com/taxonomy/term/23789/feed#comment-2062657">#permalink</a></em> <article typeof="schema:Person" about="/author/revere"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/author/revere" hreflang="en"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2062658" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1221662175"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>Interesting problem, without an easy answer. </p> <p>Using Technorati may skew the results a bit because I learned that they only index blogs hosted on blogspot.com if the owner "claims" it. That means that many bloggers who aren't Technorati savvy aren't listed there*. Also, I've found that bloggers often don't write about their "PhD"s, but do identify themselves as post docs or faculty members in their profile or "about me" page, which unfortunately doesn't show up on Technorati. And, of course, some science bloggers don't mention their educational status at all. I honestly don't think that there's an easy way to determine that information short of actually looking at each blog.</p> <p>I would argue that the actual content of the blogs is a better standard anyway, since limiting "science blogs" to those written by Ph.D. scientists excludes what I think are good science blogs by graduate students and other non-PhDs who are working scientists (like erv here at Science Blogs) and non-scientist science writers (like The Loom). </p> <p>* This was a problem when I hosted the scientiae carnival. Several of the submissions using Technorati tags were overlooked because Technorati did not actually index those blogs.</p> </div> <drupal-render-placeholder callback="comment.lazy_builders:renderLinks" arguments="0=2062658&amp;1=default&amp;2=en&amp;3=" token="8fH-T12XV6Xn_6Y8V3Z1Nmp0vDRoH0bUHzW6VqkZ0pE"></drupal-render-placeholder> </div> <footer> <em>By <a rel="nofollow" href="http://sciencewomen.blogspot.com" lang="" typeof="schema:Person" property="schema:name" datatype="">Peggy (not verified)</a> on 17 Sep 2008 <a href="https://scienceblogs.com/taxonomy/term/23789/feed#comment-2062658">#permalink</a></em> <article typeof="schema:Person" about="/user/0"> <div class="field field--name-user-picture field--type-image field--label-hidden field--item"> <a href="/user/0" hreflang="und"><img src="/files/styles/thumbnail/public/default_images/icon-user.png?itok=yQw_eG_q" width="100" height="100" alt="User Image" typeof="foaf:Image" class="img-responsive" /> </a> </div> </article> </footer> </article> <article data-comment-user-id="0" id="comment-2062659" class="js-comment comment-wrapper clearfix"> <mark class="hidden" data-comment-timestamp="1221663935"></mark> <div class="well"> <strong></strong> <div class="field field--name-comment-body field--type-text-long field--label-hidden field--item"><p>There's been a session at the recent Joint Statistical Meetings about statistics with blogs and online networks; see <a href="http://www.amstat.org/meetings/jsm/2008/onlineprogram/index.cfm?fuseaction=activity_details&amp;activityid=171&amp;sessionid=203140">http://www.amstat.org/meetings/jsm/2008/onlineprogram/index.cfm?fuseact…</a>, and may be contact the authors for ideas. Generally you will have issues with measures of size and analysis weights: how frequently messages are posted, how many people read the blog, etc. Sampling networks is yet another interesting issue, but for that one, there should be some literature around: epidemiologists have been interested in that kind of stuff for a couple decades by now, so there's been some progress made on that.</p> <p>Mark Handcock, the discussant on that JSM session, is probably the best authority on network and methods of their analysis.</p> <p>My blog engine is livejournal.com, by the way. But my blog is not solely about research, unlike say Gelman's, although I do mention some academic problems (mostly bureaucratic ones though :)) from time to time. Livejournal has the idea of communities -- usually that's where people post questions with the hopes of somebody hinting an answer, and I am a member of a dozen or two on statistics, mathematics, social sciences, public health, you name it. I don't know if that is going to count for you as a science blog.

As soon as the tenure requirements in a typical research university will say, "Publish k papers a year (k=0.5-1 in economics, k&gt;5 in medical sciences), publish 20 updates on Wikipedia on your research topics" -- gosh, Wikipedia will make all research journals obsolete in a year. And if you look into the intranets of American universities, all instructors use blackboard, which is a 3rd party tool for setting up almost all aspects of university courses -- some faculty teach 100% online courses using it.
