Your old blogs - lessons learnt?

Wow. I'm on a topic-creation spree today. Maybe because I havent had much time to come on here since a while. ;) 

So, I was looking through some of my old blogs today (and thinking I was a bit of a fool, and at the same time trying very hard not to laugh) and reflecting on how much I'd changed since then - as both a person and as a blogger. 

So the question I raise to you today is this: Do you ever go back to your old blogs or your first posts? And if you do, do you feel that you've changed? What are the similarities from now and then? What are the differences? 

Personally, my similarities from then and now: 

1) My writing style has remained more or less similar. I still write as much in lists and try to keep things neat and organized. 

2) A lot of the sites I visited then and now (from my favorite sites list) havent changed all that much. 

Differences: 

1) I've become much better at writing. (I hope.) 

2) I've become less self-centered in my writing. 

3) I've become a lot less silly and dont include books I've never read in my 'favorite books' list. (But I was a child then.)
