Hey PJ, You aren't being an ass at all. You're asking an important question, and something I've been interested in for a while. Here are some relevant threads to take a look at:
http://wiki.apache.org/nutch/Nutch2Architecture http://www.mail-archive.com/[email protected]/msg12688.html http://www.slideshare.net/chrismattmann/lessons-learned-in-the-development-of-a-webscale-search-engine-nutch2-and-beyond https://issues.apache.org/jira/browse/NUTCH-609 http://osdir.com/ml/user.nutch.apache/2011-07/msg00080.html http://5341.com/list/48/349985.html If you're interested in contributing to Apache Nutch, check this great guide out written by Dennis Kubes: wiki.apache.org/nutch/Becoming_A_Nutch_Developer Before there wasn't a ton of interest in replacing the plugin system since it "worked" and we didn't get a lot of complaints or anything. That interest turned into the perception that a DI framework wouldn't be welcome. On the contrary, I'd say if you figured out how to get a DI framework working with the existing plugin system, I can personally say I'd dedicate some of my time towards helping you shepherd it in and I think the rest of the committers would be on board. Thanks for your interest. If you have any more questions, please ask!
