Mark, you're cool no matter what!
Actually, House music is is a subgenre of electronica. I don't necessarily like the term, "electronica", because it's so broad. I like it better than "techno" though!
Anyway, here's a good definition of electronica:
Electronica is a rather ambiguous term that covers a wide range of electronic or electronic-influenced music. The term has been defined by some to mean modern electronic music that is not necessarily designed for the dance-floor, but rather for home listening. The origins of the term are murky, although it appears to have been coined by British music paper Melody Maker in the mid-1990s, originally to describe the electronic rock band Republica.
