The 30 best people in advertising to follow on Twitter

#AdvertisingTwitter can sometimes seem like a desolate land. The majority of marketers and ad execs either aren't signed up to the service or only use it to retweet nice things about themselves or their company. 

That's why we pull together an annual list of the best people in advertising and marketing to follow on Twitter.

These are the executives we believe provide the most value with tweets that are insightful, offer useful information, give us an inside look at their company, or simply make us laugh. They may not necessarily work in an agency but what they have to share provides value for the whole of the advertising community. 

Methodology: We've weighted our rankings using a (not entirely mathematical) scale of how often the user tweets, how often they engage with other Twitter users, and whether the majority of those tweets tend to be useful/opinionated/funny or simply brighten people's Twitter feeds day to day.
