Get on it. I think part of the problem with many is that when posting a theme, they themselves feel the repetition and the audience doesn't respond so much so it feels a bit pointless. I enjoy writing, but I also enjoy interacting and having a little fun around the place, exploring the corners and discussing what I find. I like to integrate parts of my life and interests into each post in some way so I myself can relate to it. I find those who just tell the news, don't seem to love what they do and that shows in the way they approach their audience.
