Well TidBITS just had their 20th Anniversary. I read them throught most of the 90s as a text file in the SETEXT format with a tool call EasyView. This was a early version of Markdown that would use formatting cues to break the text document in to chapters and articles. The sidebar would have all the different editions of TidBITS.
I while ago I wrote of my computer history going back to my Apple ][+. Well almost that old is the reading of Apple News from various sources. I must admit to have lost TidBITS in the deluge of RSS feeds that fill my reader. But last year I re-discovered them and now have them on high rotation in Google Reader.
