Don't ask users when opening the mobile app to send mass invites to anyone they have ever talked to on the phone via text message or email. I uninstalled the app as soon as I saw that.
Stop the eMail bombardment. All eMails I get from LinkedIn go directly to Spam because of this, even the useful ones. Also, cease the dark pattern that makes you accidentally invite people to LinkedIn.
They made it look like Facebook recently and it's painful to browse on a desktop. They use only a few pixels width instead of the whole screen. So, I'd fire one or two UX people. The rest is ok... also get rid of a bunch of useless notifications because no one cares about your birthday on linkedin.
For their platform to be a recruitment platform, they should fix targeting, suggested hires. The algorithms behind it are in a dark age. Their tools to load jobs and suggest skills are terrible. The ability to customise jobs is woeful and they do not really make it easy to spread jobs into groups.
Buy AngelList, let people login using their linkedin and autofill their profiles, let recruiters in a "Recruiters" group, not your "Network" which is basically a friends list.
To be honest, if I was the CEO of Linkedin, I will be happy overall. Here is why. The stock IPO'ed at $45 and it is sitting at $190 today. So I will say that it is going well. Who cares about those stupid users, eh ? Remember, the primary goal of any for profit company is to make profit for their shareholders, period. Everything else is a side effect.<p>Now, if I was the actual user of linkedin, we are talking a whole different situation.
From the CEO's perspective I'm not convinced it is broken.
