Same. When I'm checking BlueSky each day I'm usually too wiped to generate any fun lingx content myself, & instead mostly just wind up reposting critiques of AI, academia, & AI in academia 🫠 Not gonna call it a "resolution" but I *will* try to post more about linguistics here in 2026!
I wish more people posted about linguistics on bsky. Even if I try to follow all linguists, people end up talking about politics all the time. When #bsky is just another ragebait or anxietybait machine, people avoid it.
I care about politics of course, but I try to have boundaries too.

It is unclear to me how much traction Glossa: a journal of general linguistics is getting on BlueSky. I am thinking of switching communication about new papers to LinkedIn, which gives better insight into the # of views garnered. Give us a like if you want Glossa to stay on the Blue side of things.

Super cool study led by Haleh Yazdi - a simple demonstration that applying oft-used measures to novel contexts isn’t enough for inclusive & effective cross-cultural research. Measures designed for western populations do not always capture cross-cultural variability, nor within-group patterns.
A common problem w/ studies testing non-WEIRD groups is they compare multiple groups using the same WEIRD measure. How can we compare groups w/ apples-apples measures w/o distorting cross-cultural differences? We explore this in this new paper! onlinelibrary.wiley.com/doi/10.1111/...

Age is an important predictor of many behaviors & yet we know little about how children understand it. Early studies suggest they don't know much & conflate age with physical size. Here, @kostaboskovic.bsky.social revisits this consensus & shows even 3-yr-olds use multiple cues to reason about age.

New pre-print with @drbarner.bsky.social! We ask how children come to understand age. We find that young children use numerical age and facial morphology to identify who’s older, not just size, and point to acquiring a number system as key to developing an understanding of age.

Dear Chancellors:
I'm writing with regard to the President's Postdoctoral Fellowship Program (PPFP) and the program's associated faculty hiring incentive.
As you know, for more than 40 years, PPFP has provided postdoctoral research fellowships, professional development, and faculty mentoring to scholars in all fields whose research, teaching, and service advance the academic and research missions of the University of California.
Since 2003, UC campuses that hire current and former PPFP fellows into ladder-rank positions have been eligible for a hiring incentive funded by the University that provides support for newly hired fellows for five years. Since the creation of the incentive, more than $162 million has been invested by the University to support PPFP faculty hires. This commitment has enabled our campuses to successfully recruit and retain outstanding faculty across a range of disciplines.
Given the myriad challenges currently facing UC - including disruptions to billions of dollars in annual federal support, as well as uncertainty around the state budget- reasonable questions were raised in recent months about whether the University could maintain the commitment to current levels of incentive funding. After considering a recommendation to sunset the incentive program due to these significant fiscal constraints, I consulted with all of you as well as faculty and campus academic administrators and systemwide Academic Senate leadership.
