Plain Old Semantic HTML (POSH)
POSH yet another acronym to add to the list and yet a very useful term to encapsulate the need to create well structured HTML.
Let's face it there's still some horrible code being written out on the web and still a surprising percentage of sites being built with tables used for presentation. Given the take up of the Web 2.0 acronym perhaps another acronym to remind us of the fundamentals isn't such a bad idea.
