Fortune’s Dan Primack takes issue with the Wall Street Journal’s headline today that reads “Groupon Investors Give Up.” He agrees investors are bailing, but takes issue with the conclusion that it means investors have lost faith in the new Internet crop. Primack points out that Andreessen Horowitz didn’t sell Facebook shares when the lockup expired last week and that New Enterprise Associates, Groupon’s largest outside investor, has held onto its shares.
