I think I went from Usenet to MySpace to Twitter to Tumblr to Mastodon to Pleroma to Friendica, never deleted any of these accounts...
Now I'm thinking of what a federated form of a Tumblr blog, posting in a MySpace site, to a Usenet group, would look like...
Whats your internet journey? Mine is like 2009 (10 years old): kongregate chat -> 2011: reddit and minecraft forums -> 2013? reddit only -> 2015: discord -> 2018: mastodon
