According to our friends at ERE.net, LinkedIn made two announcements at its conference this week in Sydney, Australia.

First up? CheckIn. Here’s how it works: At an event, let’s say you stop by an employer booth and give your name and email address to a recruiter. Although this is technically from a recruiter’s vantage point, the talent acquisition professional can send follow up messages to you through the site. As of July, we hear this will be fully up and running.

As for the other new enhancement, LinkedIn is changing their social campaign. Again, this is from a recruiters standpoint but it’s still good to know the inside scoop. Previously, recruiters could send updates to company followers via their company page. Well, they’ll be able to do it from “Recruiter” going forward and will be able to track responses.

It’s been a busy week for the professional networking site. Earlier this week, they announced an enhancement to LinkedIn Today by introducing multiple channels. Associate product manager Kevin Gu wrote in his blog post on the site, “Through channels you can follow broader topic areas that cross multiple industries and professional sectors. By following channels you will have access to timely and relevant professional news and insights that can help you stay one step ahead and be in the know on what’s trending in your professional network.”

He added, “Channels represent a more comprehensive way to discover, share, and engage with high-quality Influencer posts, top news sources, and SlideShare content — all in one place.”
