A question for you, based on a recent conversation in which someone may or may not have been accused of being a curmudgeon:
Let's imagine there is a blog you enjoy that's built around a certain topic or theme. That topic is what drew you to the blog in the first place--you loved the recipes with their gorgeous photos, say, or reading about what it's like to live in a wee log cabin on a mountaintop.
Now the blogger, whether from boredom or distraction, is veering off topic. The recipe blogger writes about politics and her new kitten. The log cabin dweller offers movie reviews.
A blogger can write about whatever she likes in her own space, of course. But how do you react as a reader? Are you annoyed or bored by the shift? Do you keep happily reading?
Feel free to explain your vote in the comments.
ETA: Forgot to mention that the actual question at hand was is it better to post frequently and give visitors fresh content, even if it's off-topic, or post infrequently but have a clear theme.
