You can hash connections and make intros directly from Twitter.com or any Twitter client (like TweetDeck). You can also use Hashable via Twitter on your mobile device: all you need is Internet access or SMS tweeting enabled from your phone.

When writing your tweet, you can use any of our recognized connection tags (like #lunch, #meeting, #drinks etc.) – or make up your own tag like “#SXSWi”! Just include your tag, the Twitter handles of the person or people you are connecting with, and our Twitter handle (@hashable) somewhere in the Tweet. We will capture your connection and publish it to your activity stream. The connection will also be shared with your Inner Circle.
