Does anyone actually ‘engage’ in way other than trying to block their spam? Every 6 months or so they seem to break through and the crap piles up. I was just fighting them off this morning.
Millions of new posts, job searches, private messages and other activities take place everyday. They do have plenty of spam and a terrible UX but that doesn't mean the site and community is anywhere near empty or useless.
IIRC, they were about some technical topics, similar to what you'd expect to see in a blog. Why they close to use Linkedin I don't know, but apparently it does happen.
Things such as who else they work with, their exact position in their company, where they have worked in the past.
All the social features bolted on are useless to me.
