[D6 d.o. upgrade] about the pivots module recommendation block

It's very exciting about d.o. redesign and its upgrade to D6! I'm just wondering what would happen to the "related discussion" and "related modules" blocks after the upgrade. The pivot_block.module code is D6 compatible (thanks to goba's code review). Hope it's still going to be there, right?

Since my primary research focus is on recommender systems, at least in the next 3-4 years in my PhD program I'll continue to work in the project and improve the recommendation algorithm. Hope my commitment and expertise in the field could continue to be a contribution to the community.

Solr is based on Lucene, which is basically a text engine. It uses the "content-based" algorithm that generates recommendations based on text description. That might not work very well for modules because it requires similar projects to have similar project descriptions. The other set of algorithms, like what is used in the pivots_block, is called "collaborative filtering" algorithm. It generates recommendations from users collective input such as project usage, download activities, co-mentions in discussion, or voting, etc. I'm currently developing a more generic module for that purpose. Maybe I can discuss it with the infrastructure team during Drupalcon~
