Hi, the distinction between a mailing list of developers and a different mailing list of users is typically driven by increasing traffic. Either of developers or users do not want to accept too many mails, which aren't of any interest to them. That's fine.
On the other hand, the separation has also a disadvantage: It splits an existing community into two subcommunities. In the case of xmlrpc-* this means splitting an already small and weak community into two smaller and weaker. Additionally, I have the feeling that there isn't too much contact between these two lists. Upon recently, John Wilson was the only one I was aware on both lists. Wouldn't it be good to merge these lists? For example, one could move all subscribers of xml-rpc-user to xmlrpc-dev and leave xmlrpc-user as an alias?
