The old package browser was broken -- instead of trying to fix it I am creating a new one from scratch. I’ll be using the Django framework. I’m also looking into Solr and Haystack to see if they can be of some use here.
It’s not going to take a lot of time and I will publish the working portions of the Package Browser as I finish and test them. Also, we’ll have some other thing to announce in a few days, so stay tuned ;-)
