You're LinkedIn's latest advertising star - didn't you know?

LinkedIn made a bad social advertising call, but we should know better than to trust social media...

LinkedIn may have generated bad feeling by employing its users' names and photos in advertising but users only have themselves to blame for the issue, says's Jo Best.

Corporate social networking is clearly a lucrative business. LinkedIn recently went public with an IPO that raised $352m in funding. Facebook may be fine for posting pictures of your friend's party but when you want a public face to present to your next employer, you turn to LinkedIn.

In many ways, LinkedIn's success can be put down to the fact it's not Facebook. It doesn't encourage you to overshare or encourage others to share information about you without your involvement. While teenagers may have to change their name to escape from a past detailed on Facebook, I doubt anyone will need to banish a reputation garnered on LinkedIn.

Conversely, when you take these actions on LinkedIn, your name/photo may show up in related ads shown to LinkedIn members.
