This year I have resolved to keep my blog going by writing something at least once a week and reading and commenting on another person's blog at the same time.
It sounds easy and once it becomes a habit, I'm sure it will be. To get in the habit I've joined a group (Ultimate Blog Challenge) where the aim is to blog every day for a month. I didn't join till yesterday so missed the first couple of days. I will try and post extra to catch up with that.
