Actually, those are just the newest additions I’m including in the second draft. The first draft also features these milestones (including Pepys, btw):

1990: Margaret Lanterman, aka The Log Lady, begins dispensing advice and prophesies that supposedly emanate from the wooden log she carries on the TV series Twin Peaks. (It remains to be seen how much of an influence Lanterman is in blogging history, but I thought I’d err on the safe side and include her just in case.) Hat tip: Jim Long

1992: Berners-Lee launches the first website. Among his publishing innovations that year is the first “What’s New” page, a Web page that places new updates at the top of each page, pushing older items down to the bottom.

1994: Claudio Pinhanez of MIT publishes his “Open Diary,” a Web page documenting goings-on in his life. At the same time, online diarist Justin Hall would gain notoriety for creating a “personal homepage” on the Web covering his day-to-day activities in very revealing – and occasionally embarrassing – detail.

1994: Brian Lucas launches travel-library.com, a collection of online travel journals submitted by the public to the rec.travel USENET group.

Spring 1999: Online journal writer Peter Merholz jokingly takes the word “Weblog” and splits it into the phrase “We blog.” Over time, “blog” would supercede “Weblog” as the term of art for describing online journals.

1999: Development of RSS, or Really Simple Syndication. Made it easier for people to subscribe to blog posts, as well as distribute them across the Internet, such as the early news aggregator Radio UserLand. (Hat tip: Joe Germuska)
