Introduce something in March and it’s a great new feature, remove it in December and it’s another great new feature.

This has endless scope:

‘We got rid of the cluttered old front page with its random plugging of Matt and Friends and made it easier to read and faster to load!’

‘Remember the clunky rich text editor? Well, it’s been replaced by a much more intuitive editor featuring quicktags! Enjoy!’

‘We’ve replaced those silly widgets with a standard layout so that every blog you visit is guaranteed to have the same sidebar. No more confusion as you look in vain for the blogroll!’

‘We know that a lot of you have been requesting Google Adsense on your blogs, and we’ve been listening! From now on all wordpress.com blogs will feature a classy 468×60 ad banner directly below the header!’

Like I say. Endless scope.
