Wasn't Web 1.0 in a time before ads, or, depending on site, of banner ads and paid search placements that Google, sought to end?

And Web 2.0 defined by remixing, RSS, Torrents in the mainstream, Twitter, Flickr, Youtube and many more less acquired today?

I struggle to put the silod and gated repositories of members', and of non-members, knowledge and social interaction in the 'Web 2.0' bucket.

[Edit: The term webX.Y might not even apply much anymore. Quite a lot of the world is app-first where websites are an anachronism, an out-dated concept where a web browser may not be knowingly opened for a month, if ever. For many, the web is dead or not even known; today, for plural manys, it's all AppLand.]
