Linguistiblog
I now have no idea what led me to Linguistiblog a few weeks back. And I haven't been reading it regularly, because the page often fails to load properly.
But when it does load, it sometimes points to some gems. I like this brief paper on "The Hyperactive Voice" from Speculative Grammarian, which appears to be to linguistics what the Annals of Improbable Research is to other sciences.
Also, a set of brief papers on a language called Moundsbar:
...my previous note on this strange language, published in the journal Quaestio, was in error in almost every respect. Afterthought prompts the conclusion that this was due to my having obtained most of the data by telephone.
