And now, a message from our data team (hopefully addressing some of your questions on this thread):
Thanks MNers for all the appreciation and we are glad you enjoy the swearometer. We started the swearometer during the Brexit process in 2019 when we noticed that we could measure the Brexit craziness through increases in swearing on the Politics and Brexit forums, and - when things got particularly mad - across the site. We did try the swearometer for the full range of MN swearwords, but found that 'fuck' and 'shit' dominate so widely that the others made little difference and if anything made the results more noisy. Also swearwords that are used to refer to a disliked individual (eg 'bastard' or a number of words beginning with c...) are more likely to be about private individuals (eg someone's DH or DP) then a news item.
The Covid swearometer has been spot on - the peaks not written in to the Economist graph are when Boris cancelled Christmas (19th December) and we even got a small swearing peak for Dominic Cummings' Rose Garden appearance.
Mumsnet language is a pleasure to work with and as a team we do our best to show the diversity of opinion and expression through data analysis to share the difficulties faced and insight derived from our brilliant users. We have also done work in the pandemic on studying mental health related language to understand the impact on mental health of both parents and children throughout this pandemic (we found that concern for children's mental health peaked last August before the return to school and during the recent set of school closures).
We'd love to hear what you think we should be looking into too!
