Do you prefer short blog posts or long ones?

Just a question to the people reading this.. do you prefer reading something thats short or long?

Only reason I ask is that on my other blog http://techdude.co.uk/, I don;t get to post often, same as on here, so I only write short paragraphs to sum up what I want to say. Do you like this approach or do you think I should try and make them longer?
