my father (75yo) still obsessively updates his personal website (using FrontPage!) For years he was proud that his article on Hill's Criteria of Causation was the top hit on google for a search on "hills criteria" or similar. At the time Wikipedia had no article on it (he's now #4 since wikipedia has a article as well as a couple of medical sites.)

His site has the look of a personal webpage from 1997, but since retiring, he still works on articles and publishes them on his site. His site is a mix of scholarly articles (Anthropology), old syllabi, and personal stuff.
