So we've heard alot about brands jumping on the Twitter bandwagon but other than ispylevis I haven't seen any campaigns by which I've been wowoed.
This however, is a nice concept from Nissan.
Its a site that profiles your 'Twitter' personality. Check it out.
The reason it works is because it is not obviously branded. I clicked on the link because one of the people I follow said it was cool and then before I knew it, I had been profiled & tweeted it on for all of my followers to see!
Its a nice way to leverage a social platform that is relatively new to the masses.
