Do you remember when you could only view a census page in a small "viewer" box? And you couldn't download the entire page in one file?
Do you remember when Ancestry didn't have all the census records from every city and state, let alone all the decades up to whatever the privacy cut-off date was at the time? And the census images that it did have weren't all indexed?
I'm pretty sure they didn't have a place for family trees, either: wasn't that what we went to Rootsweb for back then?
People could choose to allow you to download a gedcom of their family tree from Rootsweb, and I think I recall having that option for a time after Ancestry started providing a place for family trees. Do you remember when they removed that option and why?
It's so much easier now for people to create and build a family tree, especially with the hints and being able to click a button to have the system add people for you. (You'll notice I didn't say their trees were necessarily populated with sound research, but we all know about that, don't we?)
I think we get much more bang for our buck nowadays, especially compared to what was available 20+ years ago.
