Sorry for this being the latest wrap-up ever.

May was a fun month for us. We rolled out a ton of new features: the ability to add YouTube videos and polls to comments, stats in your time zone, the VideoPress upgrade (with HD!), post by email, new stats charts, comment search, improved comment reply by email, and VideoPress.com.

May was also the month for our largest-ever WordCamp San Francisco. Mission Bay Conference Center was a packed house, but (amazingly) everything ran on schedule, and nothing went wrong! A round of applause is due to our sponsors, speakers, and everyone who attended for helping to make WordCamp such a smooth success. Thanks for making it all possible.
