I learnt Prolog in the late 80s at Uni, when even then, it was a pretty odd thing to be interested in. It's nice that the community has kept going with it as an intellectual idea. I'm wondering what contributions it has made to the wider programming community. I guess things like the warren engine may have helped inform efficient methods of interpreting other languages, or the parallel prolog investigations probably again helped other languages. It's pretty clear to me that functional languages from the time (e.g. Miranda) which live on it Haskel have had a massive impact on modern programming languages, and approaches to resolve complex threading problems. I've a feeling the prolog innovations may be quite wide too, just maybe less obvious.
