These are a bit rough, so please add to them:
A few of us are making hosting changes, so we chatted about hosts awhile. Sheila is doing a lot of research on this specifically. Maybe a topic for the future?
We mentioned Ipstenu http://ipstenu.org/ the WP / Hosting genius who has helped Taylor and Mark on occasion w/difficult code chunks.
Mark has updated his blog and has been cranking out some solid work.
