Why does Thingamablog republish my entire blog every so often?
Thingamablog does this to keep the pages of your blog up to date after a rebuild. Whenever you post a single entry, Thingamablog only publishes the pages that have changed. However, whenever a new archive page needs to be created, all of the pages of the blog need to be regenerated to reflect the added archive. Therefore, the entire blog gets republished. Additionally, changing options in the Blog Properties dialog causes the blog to be rebuilt.
