consistent

Something that has always bugged me is how people suggest good bloggers should be consistent with their content.I don't understand why this medium of new media needs to comply with traditional media practises.My Dad reads his newspaper every morning. Therefore his news paper must land on his doorstep at 6am each day. But I don't read the newspaper, I have an my RSS Feed. I want things to come in as they are published, not once a day at the same time.I try to post every second day. But sometimes it's longer and sometimes it's shorter. People subscribe to my blog and pull my feed into their reader when a post is published. So why does my content need to be consistent?...
