My First Blog

Well I'm trying this blog thing out. I've never blogged before and would like to see whats the big deal. Is it better for people to put ideas and thoughts into words? I'd like to hear from the many bloggers out there on their reasons for blogging and if they have any tips or ideas for a newcomer. I don't even know how people can be so consistent in blogging. I think I'm done after this blog..lol
