Hey everyone! We tried out Apache PredictionIO a while ago but it seems to be unmaintained and soon to be moved to the attic. This seems like a promising replacement as ActionML was one of the commercial maintenance providers for PredictionIO. We haven't used Harness before though, so I would like to hear your thoughts on it!
I'm also interested in hearing if anyone has info on what happened to PredictionIO and why companies haven't really adopted it.
