I’ve never really had any cause to write large posts using WordPress, except for my NSLU2 guides – and even then the built-in WYSIWYG editor was good enough, albeit a little clunky and requiring gentle persuasion every so often.
But after changing blog themes the other day, I realised the NSLU2 pages were actually quite dependent on the underlying CSS – and for some themes, this means that they looked rubbish.
