Subject: [DCHAS-L] DCHAS-L 2021 statistics

Back in 2015, I presented a talk titled "12,232 Thoughts on Laboratory Safety in 25 Minutes or Less" at the Boston ACS Meeting which was based on Ralph Stuart's and my effort to ensure the pearls of wisdom on the list are forever preserved: https://acsdchas.files.wordpress.com/2015/08/m3-toreki-12000-thoughts.pdf  

At the time, that's how many archived posts we had on this listserv. As part of that talk, I had constructed a top 25 list of posters and topics by year for comparison. I couldn't remember how I automated that, so I decided with the new year I would figure it out again so I can start this as an annual New Year's tradition.

2021 had less traffic than the past several years: 1,536 articles. The total number of posts is now 24,833. Ralph wears a couple of hats, so it is no surprise he captures the top 3 slots by poster. The top 25 posters of 2021 were:

Name # of posts
Ralph Stuart 178
Chemical Safety Headlines 150
CHAS membership 131
Monona Rossol 58
Richard Palluzi 56
CHAS membership chair 44
Rob Toreki 40
James Kaufman 31
Neal Langerman 28
Yaritza Brinker 27
Jessica Martin 24
Eugene Ngai 23
Jeffrey Lewin 22
Peter Zavon 21
CHAS imap account 20
Margaret Rakas 19
John Callen 18
Debbie Decker 17
Jack Reidy 16
Alfred Barksdale 15
Dr Bob 15
Peter Reinhardt 13
Tilak Chandra 13
Harry Elston 12
Monique Wilhelm 12

For the subjects, I wrote a script that figured out each topic and counted all of its replies. The one exception is the line titled (original CSH posts only) which does NOT count replies. As you can see, the # of CSH posts corresponds to the number by poster Chemical Safety Headlines above, and is consistent with a normally 3x a week headline delivery.

The top 25 topics of 2021 were:

Topic # of posts

The full data set is available if anyone wants a copy. I can also generate past years' stats now that I wrote down the Excel procedures to use after my script extracted the data.

Best wishes to all for a safe, happy, and prosperous New Year
