Current Linkstream2 microblog (Jan. '12 onwards)
I have a special page describing my key tags and other bits of the blog.
Also, I have a mirror site that has a page listing all my tags alphabetically or by frequency, up to Nov. '19. Then I have some simple dumps of recent tags.
My microblog reformatted in the new blogger style. (Note, this is only an approximate mirror of the main site.)
I have gotten quite into tagging (where these function as attributes for various linked entities). Here's an old post on my philosophy
My original linkstream blog
Some old public tags (PIM-Public-Tags)
For fun, I've tried to make my old delicious tags available in a variety of formats.
I also have cached copies of my very old Backflip bookmarks (020826, 20-Aug-06) and even older ones (before July 2000)
