In this video from the Motley Fool's "Ask a Fool" series, Fool analyst David Meier takes a question from a Fool reader, who asks, "Do you think Twitter (TWTR) will maintain its stock value when they have made no profit vs. Facebook (META 0.14%) who is profitable?"

David reminds investors to think of Twitter not in terms of its current profit, but of its future profit. He highlights strong growth in three categories: the service's number of users, the number of advertisers coming to the site, and the amount that each advertiser is spending. While it's unclear whether this is a recipe for growth that will drive Twitter to reach the size of Facebook, David feels it will certainly drive major revenue growth for Twitter down the line.
