As far as I was aware a blog could be whatever the blogger wanted it to be. Freedom of speech and all that? It's not for anyone else's benefit but the blogger's. If people decide to read it all the better, but for me, It's always been nothing more than a place to go to vent and ramble and just let some of the pressure from my head drain. I'm not here to preach. I have little wisdom or juicy gossip to share.
If people don't like that, or think it's boring, or egotistical that i just tend to ramble about my day, and post the odd song I've written, to be honest, they shouldn't have bothered wasting their time reading it.
I do this for me.
