Hashtags are all the rage at conferences these days. These strings of text preceded by the # sign are the de facto way that users of social networks flag their posts as belonging to a specific topic, location, organization, or event. At conferences like Mark Logic User Conference 2010, users of Twitter and other social networks will add #mluc10 to their posts in order to help automated tag-aggregation systems like search.twitter.com or hashtags.org combine all the tagged posts into one big feed.
Adding hashtags to conference-related posts on services like Twitter makes it easy for conference attendees to see what’s going on around them, in other sessions in other locations at the event, and to gage the public opinion of attendees who are participating in the conference. Adding hashtags to conference posts also provides people who were unable to attend the event with a way to follow along from home or the office.
Here’s what a small selection of posts looks like when they are taged with #mluc10 and are automatically combined together into one feed.

Ensure your posts show up in the aggregated conference feed, include the #mluc10 hashtag in the body of your post. And, if you’re interested in learning more about hashtags on Twitter, check out this hashtag primer.
