You get to look back at your old posts in astonishment at how far you’ve come from back then. Take Paul Stovell for example.
In March of 2006 he gave a presentation called "Why I hate Data Binding"
In July of 2007 he gave a presentation called "Binding Oriented Programming"
Talk about an about face! I don’t have any drastic examples like that in my blog. But it’s still fun to read through some of my old posts.
