If you make a cool craft, or have a deep thought and don't blog about it...did it really happen?

I've been thinking about my motivations for blogging. I really am not sure why I do it. It has come to the point where it seems like I need an audience. And not just me, but everyone who is addicted to social networks. I mean, we can hardly have a thought without posting it for everyone to see. Sometimes we don't have a good thought to post so we just write "bored" and everyone "likes" it on facebook. It started to make me wonder if I shouldn't just quit this little blog. Can I be content to have a thought and just let it live in my head? Or only tell it to one or two other people? Can I make a fun craft and be content knowing that the only people who see it are the people who come to my house (not a lot of people)? And then being a crafter and hopeful-someday-artist I realize the benefits of an online presence because allowing others to see your personality helps make a connection to your work and increases your business prospects. But in the end I think that also has the potential to turn us as people into a brand and become a fad or a trend or maybe even a person that I am not. I don't know if I want to do that either.

I am not saying that I think blogs are bad. I have loved blogs ever since I discovered them and have had my own blogs since I was a teenager. I think they make great outlets, journals, and are great for gathering inspiration, ideas and making connections with other people. And if you have a good thought or a great process to share it really can enrich other peoples' lives. If you are just being yourself and sharing that with others I think it's refreshing and encouraging to connect with others in that way. But for me I sometimes question why I do this and whether I should do it at all.
