Being the buttoned down, older man of Web 2.0 Linkedin has decided to go with a closed developer platform a la iPhone. Which means those of you wanting to develop the first nude-office-party-photo-competition-app might struggle to get in. Shame.
In the mean time serious app developers should get going and you may even be able to charge for more serious/profound/branded apps. Ooh - money. Mind you Linkedin users will only be allowed to download a total of 15 apps on their page. App gridlock? Na, Linkedin platform constraints.
