From the article that they acquired a professional social networking app so their intention is clearly to be like LinkedIn - real names, links, career history, "social". They want to monetize that information to sell to recruiters and salesmen.
So basically they're nakedly greedy and they continue to suck. I thought LinkedIn was awful but Glassdoor is a whole new level of awful.
I've never seen much reason to use a real name on Glassdoor. They demand visitors sign up to see information, and every logon it demands more details. So I am glad I used a throwaway account and I expect many others did too, or filled it in with junk. I hope their database is poisoned with garbage. I'm sure they will continue to turn the screws - using a mobile device? You MUST use our app etc. I hope people realise that LinkedIn already sucks and here is something even worse moving into the same space.
