Admittedly I study some really obscure stuff. Literary linguistics is a very small field, comprised of even smaller fields. A lot of people in literary linguistics are really interested in metaphor and figurative language (how it works, what it does in a text, how we understand it, etc), and I know a few people who are getting their PhDs in metaphor (yes, really.) I subscribe to a few literary linguistic mailing lists- these mailing lists are ridiculous; someone with the last name van der Boom manages one of them (I love getting emails from Ms van der Boom for entertainment value alone.)
Sometimes I get emails like this:
"The 2011 [redacted] Metaphor Festival
Thursday 8 to Saturday 10 September
The [redacted] Metaphor Festival is an annual conference on the use of figurative
language, arranged by The Department of English at [redacted] University. It
brings together researchers from a broad range of academic disciplines, working
within different theoretical and methodological paradigms -literary as well as
linguistic - in a creative, internationally oriented and friendly atmosphere.
The importance of figurative language is now generally recognised, and the
Festival offers an opportunity to present and learn about research findings
concerning figures of speech in different types of discourse, and their
cognitive, cultural, narrative, poetic, rhetorical, social or textual functions."
I don't even know where to start with this.
Listen; I am currently working in corpus stylistics, which is not a big field in my already-tiny subfield of the intersection of linguistics and literature. It's like a subfield of a subfield. But it's always comforting to hear there's people working on something much more ridiculous than me.
