LinkedIn integration was introduced to welshare. It’s currently at an experimental stage. Note that some features are unfortunately missing – you can’t see your LinkedIn notifications (you can’t see them on LinkedIn anyway), there is no statistics or missed important messages yet. But as LinkedIn is one of the biggest networks it’s worth integrating and these features are coming soon.
Sharing and resharing to LinkedIn is disabled by default – you have to switch it on for each post. This is so because it is rarely appropriate to post cat pictures and fail videos to your professional and business contants.
