Reinventing the wheel

I have started a twitter account that I use as an input timeline for simple events in my life, in a way of a diary. I like to post microdescriptions with pictures, so I use FourSquare.


Who am I kidding? Am I trying to reinvent the wheel? Shouldn't I be using a blog and keep it private? Can I keep a blog private? 


Should I send myself e-mails like this dad did with his daughter? http://www.youtube.com/watch?v=R4vkVHijdQk


At the end of the day, if I chose that complicated ForSquare-Twitter path is because it was the combination at hand the moment I thought about doing it.


I think I should dig a little bit more.
