Wow. You just made me realize that most of the big changes I'd mentally spread out over 20 or 25 years happened just in the last decade. In 2007, I was considered a pretty high-tech guy for just having a blog and being able to edit it. It was still possible to add entries to Wikipedia about things that were not super obscure or recent news. phpBB forums still ruled the Internet. And reddit was a toddler!

It has been like that C. S. Lewis quote - day by day, it felt like nothing big has changed, but looking back, everything is different.
