Over Two-Hundred Education & Science Blogs * † - Department of ...

On 26 February 2009 I used Technorati’s Advanced Search
to search in all blogs (not posts within blogs) for:
1.”Education”......... 28,842
2.”Science”............. 26,032
3. “Physics”.............. 2,484
NOTE : These searches seem to require a “work around”: first do a “keyword” search for
the word “education in all blogs at to obtain on
26 Feb 2009 1,193,491 hits. Then switch the left top button in “Try Filtering your results”
from “Search Posts” to “Search Blogs” to obtain 28,842 hits.
The Technorati Authority (TA) of all the blogs listed in this compilation was found on 1-7
March 2009 by searching for their italicized titles in “All Blogs” as above. The TA’s so
derived are shown as “[TA=N]” directly after the URL for each blog, where, again, N is the
number of blogs linking to the website in the last six months. The notation “[TA=??]” means
that the TA was not found at . The TA’s for the
over 200 blogs of presently listed range from 1 to 29,972 for the Huffington Post.
NOTE: The Technorati search engine is somewhat eccentric - sometimes: (a) a search for a
blog titled “X” by its author yields nothing, but subsequent searches for “X” find something; (b)
searches of “X” in Feb 09 found relatively large TA’s, but later searches for ”X” in March 09
found no TA listed.
3. Blogged
At it is stated that (my italics; my inserts at “. . .
.[insert]. . . .”):
The blogs in our database are reviewed, rated . . . .[how?]. . . ., and categorized by editors . . .
[their names are not revealed :-( ]. . . ., so you won't experience the frustration of filtering
through blogs that are spam, outdated, or irrelevant. You'll be able to find quality blogs that you
would be unlikely to have found through a traditional blog search. We also offer time-based
searching, bookmarking, sharing, and feedback functions. Anyone can review and rate a blog
and help it rise in the rankings. . . . .[To submit a blog go to
and click on “submit a blog” in the right-hand column.]
Blogged’s rating scale is:
10............ superb
9.0-9.9..... excellent
8.0-8.9..... great
7.0-7.9..... very good
6.0-6.9..... good
5.0-5.9..... average
4.0-4.9..... below average
NOTE: Since anyone can review and rate a blog and since the identity and qualifications of
the editors are unknown, it would seem that Blogged’s Ratings (BR) must be considered
with some caution.
