One of the blogs that I subscribe to typically publishes a new post every day, or at least several times a week. But without any warning, they went totally silent for more than two weeks. This makes me wonder: how long can you take a breather before it becomes the sort of hiatus that you need to tell your readers about? For daily blogs, even 2-3 days is probably worth saying something about before you head off. For weekly ones, I’d say two weeks without a post is the cutoff point. And for monthly ones, well, I’m not sure those even qualify as a blog in the first place. Either way, it’s nice to give your readers a heads-up before you depart, including a rough estimate of when you’ll be back.
