Could you maybe consider fixing the issues that have been happening all over the service today? Such as Special:Preferences not loading (erroneously claiming the user is logged out) and the whitescreens that appear on substantial articles (despite the edits going through just fine, though is causing problems with things like Null Edit and WhatLinksHere as these aren't updating).

The problem with Special:Preferences seems intermittent, as I can now get to my preferences (despite it telling me 30 seconds ago that I'm not logged in), but these should be looked into.

Not that I'm ungrateful for the blog post, but I'm surprised that nothing has been mentioned about the issues on the service today (the editing thing doesn't just affect me, it happens with other users and has happened to me on a number of wiki's)
