I'm trying to automatically insert <!--nextpage--> into all posts after a certain word count. Seems like it should be easy, but it's not.
(AJAXed WordPress seems to be the only plugin that provides a similar functionality to what I need, but in order to use it you have to deal with the other 95 things that plug-in does and I'm trying to avoid that.)
Before you tell me that nextpage is bad for usability or I shouldn't breakup pages mid-sentence: I know. I need to do it anyway.
I'm a reasonably good coder so if you just want to point me in the right direction with a php snippet or something, that'd be great. I'm just hitting a brick wall here.
