Tim and I did a first pass on prioritizing the backlog yesterday.  Results are here:

https://www.mediawiki.org/wiki/Wikimedia_MediaWiki_Core_Team/Backlog

It's useful to understand our definitions of priority for purposes of this pass.  "High priority" means "we need to explicitly consider this idea as something we do next quarter", and it also puts additional onus on us to make sure that it's well-defined and well-scoped.  "Medium" means "we should consider this idea as something we do next quarter, but we may not get around to an explicit conversation".  "Low" means "we're almost certainly not going to give this serious consideration for next quarter".

If there's something you feel needs promotion to a higher priority, either make the case on the talk page, or be bold and make the change.  Early in the planning cycle (i.e. now) I'd like to encourage you to be bold.  As we get closer to the end of the planning cycle (July 16 review), I'll request a little more rigor before making changes.

Thanks

Rob
