Your personal page is likely largely static (in content, if not tech) and defined by you, the site owner. Web 2 allowed the public site users to generate/curate the content on the site.
This is happening again now with the web3 fad. A new generation of gullible idiots and sociopaths to take them for a ride.
This distinction only matters with centralized platform like AOL, Medium or Facebook though. Wikis existed long before big companies hijacked the web.
