As eagle-eyed readers may have spotted, the twickerati site is not a hand crafted piece of work, where each component is lovingly built, one line of code at a time by a team of specialist programmers and designers. It is in fact a theme (aka layout) from the blogging software outfit, The theme used by this site for the past 6 months is now being “retired” by WordPress and replaced with a new theme with more options for customisation. Over the next couple of weeks you might notice a few changes in layout or even one or two things that don’t work. If you see a change that you like, or even one that you don’t, please shout. And just for info, the site is already running the new theme. You’re right, there’s hardly any difference which means any format changes you see are likely to have been optional… and reversible.
