Generic 'Street Culture Blog' replaced with a tagline that matches
the actual editorial angle from about.md ('guide to the anatomy of
online attention', 'lifecycle of hype: birth, peak, collapse', 'when
the hype is gone, all that's left is a 404'):
'Street culture - Anatomy of online hype, from peak to 404'
Flows through to <meta description>, og:description, twitter:description
and the visible header tagline.
