Rob and Ralph,

Thanks for the subject information.

All and especially Monona,

Please don't look at the stats and number of posts as, "Having a Big Mouth, etc.," but rather as contributions to the "Greater Good" of DCHAS on the basis of our personal and collective experience and expertise. 

Thanks for 2021 and looking forward to 2022 Posts!

Be Safe, Stay Healthy and Happy New Year!

All My Best,

John

Thank you for the analysis. Really informative. I suspect the data miners will go crazy with these data.

Have a safe and prosperous 2022.

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
(original CSH posts only)	150

[DCHAS-L] Chemical safety communication challenges	10

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
