reading through your old posts can give you ideas, however I don’t feel this is such a good idea at the 5 month point, which is usually when I get writers block! The reason being, there are usually too few articles on the blog to start re-hashing what you have already written.

I find that a better solution for new blogs (under 1 year), is to go read other blogs along a similar theme to your own & whilst I do not advocate copying other peoples work, this method can very often give you fresh subject matter which you would then write in your own words!
