Definite "+1" ... or maybe "+100"... to consistency. That is the key. Look at anyone who you consider a "successful" blogger and I think what you will find is that the key point is that they keep showing up with new posts. And doing so on a regular basis (which for some is daily, some weekly, but most at least a couple of times a week).
"My job was to write twelve posts a day about 'media gossip,' which meant anything unpleasant or otherwise intriguing about anyone who had power in any Manhattan culture industry. There had to be enough posts so that whoever was sitting at my old desk at the publishing house, and everyone in Manhattan like her, could read something new when boredom struck."
