"Impressions are fleeting things"
"Today the language of advertising is dominated by the notion of impressions: how many times an advertiser can get its brand in front of a potential customer’s eyeballs, whether on a billboard, a Web page or a NASCAR hood. But impressions are fleeting things, especially compared with the enduring relationships of followers. Successful businesses will have millions of Twitter followers (and will pay good money to attract them), and a whole new language of tweet-based customer interaction will evolve to keep those followers engaged: early access to new products or deals, live customer service, customer involvement in brainstorming for new products."
