In those days the term used for that style was "acid house". It then turned into various sub-genres (rave, trance, etc). Acid techno is a later name for later genre.
Does anyone else find the amount of sub-genres in electronic music excessive?
I've often said the same thing. I think when there are too many, it's not useful (though in some very real sense, every artist is its own genre), but of course one genre is useless too. Some people say "why have any genres at all", but as someone who's tried to explore musical connections where I haven't been able to find established genre names -- like between old folk music from some smaller countries, or the continuum of music featuring accordions, horns (especially trumpet and clarinet), acoustic guitars/lutes, and strings that goes from Russia down to Turkey and beyond -- it can be really painful to find related music and artists without good genres.
The trick is a good balance, and I personally find that electronic music and metal (as another poster mentioned) have genres that are often too small for my purposes.
