For me it happens in cycles. I get inspiration to jazz-up/re-write my blog and that gives me a nudge to write something, anything really, just to get to see something new and that gets the rock rolling and I end up writing half a dozen posts in few weeks. Then I get distracted by some other project or a game or whatever and I forget writing for months and when I remember I have a blog I feel like I don't have anything "worthy" of writing. Until I again get inspiration to start working on the code side of the blog again and the cycle beings a new.
