LinkedIn is upping its search game, at least through the mobile app. You can now search for keywords in your own feed of updates, search for topics to see who’s talking about something broad or specific and click through hashtags to see what’s been posted using those. Right now those upgrades are available only on mobile, unfortunately, But these are significant updates, regardless. Being able to search your own updates is great for those of us who say “oh I saw an article about that a while ago” but can’t find it. Topic search can open up a world of subject matter experts you can connect with and follow. And hashtag search is…well…hashtag search. In my own experience hashtags aren’t widely used on LinkedIn, so this may not be super-useful, but it’s table stakes for social networks so it makes sense that it was added here.
