Clickable hashtags are a major new Facebook feature, and now the social network is bringing them to the next level by rolling out related searches and mobile availability. We're talking about its mobile site and (unfortunately) not its iOS and Android apps, making the former a better choice for browsing public status updates on the go. The introduction of related searches also makes it easier to discover new conversations, as searching for a particular hashtag brings up similar ones. Facebook analyzes which terms are often posted together, so looking for #equality also brings up posts tagged with #lgbt or #pride. These updates will soon show up on your accounts if they haven't yet, and unless you despise hashtags, they're icing on the cake.
