I am a postdoc in philosophy.
I contribute to a blog for philosophers who use LaTeX. If you fall in to that niche, check it out: PhilTeX. (The blog will be of use to all kind of humanities scholars using LaTeX, I imagine, but it was started by, and is run by philosophers...) The blog is currently defunct, but may be resurrected soon.
I made this beamer colour change package that slowly changes the colour of structure elements of beamer presentations. Feedback welcome.
I also made this
moreenum package which adds new enumeration options.
The TeX goodies page of my website includes some other bits and bobs I've done.
