It's been about 50 years since we discovered the "[commercialized] never-ending serial"; we still haven't realized that it's a bad idea. TV shows (and soap operas especially), MMOs, blogs; all should really have definite endings and closure, but they continue, after having done all they've set out to do, based on brand alone.
It's not like the same people can't make something else, something new--for example, you could put all the writers, artists and actors of the Simpsons on a new project, if you like--but they don't need to do the Simpsons any more. It's done. Every possible angle, every single side-story, every inter-character meeting has been explored.
1000 posts is enough to say what you came to say. If not, maybe go back and delete a few, distill some points to free up room for new expression. Perhaps blogging software should have a million-character limit on the total aggregate length of post body columns; it seems to have encouraged tweets to be more well-thought-out (though some of that is also probably from the fact that the ones sent from phones cost money.)
