Most of the top tier directories are gone, but I found 7 directories, still alive, that have been around a long time.
This is an impressive list! Not because these are very good directories—I struggled to find any new links that were of use—but a) because they are actually still there, b) the categorization systems that some of them use are different, c) some of the most interesting parts are not the actual directory (e.g. the editoral guidelines are useful—they’ve been in this game a lot longer.)
I wonder if any web portals still exist. It was such a fad and—while I never got into them—I wonder if the idea is still plunderable. I suppose the current Twitter/Facebook newsfeed is a progeny.
