Here’s the equivalent public library blogs post, for whatever commentary I provided then.

Even more so than total comments per blog, the blogs in *Academic Library Blogs: 231 Examples* lack extreme cases of high interactivity on a per-post basis: The highest is 2.2 comments per post. The overall average (an average of averages) is all of 0.12 comments per post–basically one comment for every eight posts. The median, of course, is zero.

Raw quintiles Q1 and Q2 (since Q3-Q5 are entirely zero):

- Q1: Most comments per post: 0.17 to 2.20 comments per post

Average: 0.51 comments per post.

Median: 0.33 comments per post. - Q2: More comments per post: Zero to 0.17 comments per post

Average: 0.08 comments per post

Median: 0.07 comments per post.

And using the 86 blogs with at least one comment as the universe:

- Q1: Most comments per post: 0.50 to 2.20 comments per post

Average: 0.91 comments per post

Median: 0.67 comments per post. - Q2: More comments per post: 0.25 to 0.45 comments per post

Average: 0.33 comments per post

Median: 0.31 comments per post - Q3: Average number of comments per post (18 blogs): 0.14 to 0.25 comments per post.

Average: 0.19 comments per post

Median: 0.18 comments per post - Q4: Fewer comments per post: 0.08 to 0.14 comments per post.

Average: 0.12 comments per post

Median: 0.13 comments per post. - Q5: Fewest comments per post: 0.01 to 0.07 comments per post

Average and median: 0.03 comments per post.

Two more (illustrations) and I’m done…
