Linkedin is as good as the network you have. Obviously nowadays is hard to be that selective with the people you add, but you can be with the people you follow.

Linkedin is as good as the network you have. Obviously nowadays is hard to be that selective with the people you add, but you can be with the people you follow. I use LinkedIn for 2 things mainly: 1) to build reputation, sharing articles I find interesting about my broad area of expertise and fostering some discussions. These articles are not set to create maximum engagement, because I care about my direct network creating a certain view of my experience based on diacussions with me. 2) to recruit. I use it actively to search for key profiles (lots of devs) for my team. As my big corporate HR department is very ineffective, I take my time to search for interesting candidates and send them to be contacted by HR for some straightforward filtering (interested in the position, salary, etc). For more senior positions, I contact the potential candidates myself (to avoid HR screwups). It is a very efficient tool for recruiting IMHO. So, if you don't like LinkedIn just build your profile and keep track of the inmail for contacts, as people will use it more and more to reach out to you.
