I noticed that Apache project user mailing lists (e.g. JMeter, Lucene, and Solr) heavily rely on mailing lists. As far as I'm concerned, this is old school. IMO, Stack Overflow is a superior way for Q&A. To clarify: I'm talking about the user mailing lists--not the dev contributer mailing lists.
Posting Apache project questions to Stack Overflow is not the fastest way to get answers. I have posted two straight-forward questions (one JMeter and one Lucene/Solr) on Stack Overflow. One I ended up answering myself, and the other I ended up emailing a dev contributor. I kindly asked him to post his answer on Stack Overflow, but he declined. Instead he posted on the Solr mailing list.
Mailing lists work. But Stack Overflow is better, IMO. And I wish mailing list users would convert.
Does Stack Overflow Inc (or the community) desire or plan to convert mailing list users over to Stack Overflow?
