NEW YORK (TheStreet) -- Twitter is expected to introduce four new metrics and hopes it will show that it has a wider audience who may not necessarily be logged into their accounts to reassure investors that it's a big mainstream product, the Wall Street Journal reports. The new metrics are expected to launch when it reports second quarter earnings on July 29, with the aim of changing Twitter's perception as a social network to something similar to Google's YouTube, whose videos are often embedded on other sites, the Journal noted.
