For the last few years, the blogging schedule I've stuck to was new posts every Tuesday and Thursday, and the Reference Question of the Week on Saturdays. Over the last couple months though, I've felt that I'm both running out of things to say and have less free time to work on posts, so I've decided to cut back to just one new post a week and the Reference Question on Saturday.
Not a major change I know, but it feels major to me because it's a schedule I've stuck to for so long. I know a schedule isn't mandatory for blogs, and most people probably just post only when they have something interesting to say. For me though, I think that if I didn't make myself stick to a schedule, I'd quickly slip into nothing at all.
So anyway, again, I don't know if anyone would have even noticed if I didn't say anything, but there you go.
But I am curious about the schedule/no schedule thing, both for personal and library communications. Does you're library have a set goal or schedule for blog posts, tweets, email newsletters, etc., or do you only do it when you've got something to say? In my library, it varies: I try to have a new blog post once a week, but Twitter is much more as-needed (in addition to automated tweets for library events). We have a main email newsletter that goes out once a week, but also sort of a childrens supplement which only goes out when the Childrens Room has something specific to communicate.
It seems like all models work in their context, but I'd be curious to hear if other libraries have had success following one path or another.
