Linkedin may be the worst social site around. Why you might ask would I say this? Let's look at what I see since they were acquired by Microsoft Corp., a company with poorly made products and terrible technology.
They are cheap and get infected constantly. They have the worst support of any company online today, and most people don't use their programming language anymore, with only 7.7% of sites using it. Finally, most people prefer stability, and Microsoft Corp. is far from that.
So they purchased LinkedIn, and things started breaking that shouldn't. Our posts have disappeared, yet our competitors are still working as a developer; that shouldn't be the case as these are all controllers. I'm guessing the people at Microsoft don't understand PHP. They charge a ridiculously high fee for the premium account and yet give you nothing for it.
Their adverting costs are three to four times that of Facebook, and they are ten times smaller than Facebook. They think they are worth it, but I tried to advertise, and for $500, I received nothing. I ran an ad on Facebook and received a 7 percent response.
Everything about Linkedin is terrible. It is just another Facebook app. What once was a professional site has turned into how many likes or comments I can get. Microsft has destroyed this company in a short time, just like everything else they touch. Like their founder, they are brain dead and haven't a clue. Yeah, they believe that he is brilliant because Bill Gates invented this MANY years ago. No, it means he did it first, and now they are dead last with everything today.
