Mark my words: the next fad in web design* will be huge (and I mean really big huge) headline text.
It started with Zeldman's redesign and continues on a new, bold (pun intended) level with the Coudal Partners redesign.
Who's next?
* The previous fad, still prevalent today, is the re-emergence of a huge picture with little apparent relevance to the site. (Gee, that's so artsy! I love artsy.) Coudal gets bonus points for clinging to this fad while at the same time furthering a new one.
