Blog Much?

Woah, so it's been such a long time since i have even thought about using a blog, i mean fooorever. What do people write about? Their lives? Their families? Their hobbies and interests? This is crazy, I'm just myself, and just because I like something doesn't mean anyone else will like it right? So what is the point of a blog? I guess my opinion of a blog is just to write how i feel, what's new, and what's going on in my life, kind of like an online diary? Guess we will see how long i like doing this, if i ever get the hang of this thing! :)
