Make Sense of Confusing Twitter Hash Tags

Do you use Twitter, but don't spend your March in Austin? You may be confused by "#sxsw" showing up in your stream. A new site can help make sense of the gibberish "hash tags" spouted by some of the people you follow.

Hash tags are words or acronyms that begin with the number sign. They are used when many people are tweeting about the same topic, or from the same event. At least one hash tag is often atop Twitter's trending topics list. Tagalus is a service to declare the meaning of those confusing hash tags. There can be more than one version, with users voting up the best definition.

Just send a tweet @tagalus to suggest a meaning for a tag. You can also add and view tags on its site. Even better, Tagalus has an API, which accesses both getting and setting of definitions (more at our Tagalus API profile). The usefulness of hashtags could really be increased if Tagalus is integrated into popular Twitter clients, the same way automatic URL shorteners make sharing links easier.

Tagalus isn't alone in trying to make sense of hashtags. The granddaddy is, which tracks tags by popularity over time. Before Twitter's search feature was useful, Hashtags provided a means to search tags. Tagref, a tool similar to Tagalus is built on Twitter's APIs (our Twitter and Twitter Search profiles).

Like Twitter itself, hashtags have multiple uses. Services like Tagalus are helping to make sense of the possibilities.

Does anyone have numbers on the number of #hashtags used on Twitter on a daily basis right now?


saw a new hash tag #BrnSt on <a href="" rel="nofollow">Emotional Brain Training News</a>. I think it means Brain State or a way to describe how stressed you are, 1-Feeling Great, 5-Stressed Out.

Much easier way of explaining how you feel to other people in your network.

Hi! I know this is kinda off topic however , I'd figured I'd ask. Would you be interested in trading links or maybe guest authoring a blog post or vice-versa? My site covers a lot of the same topics as yours and I feel we could greatly benefit from each other. If you are interested feel free to shoot me an email. I look forward to hearing from you! Great blog by the way! <a href="" rel="nofollow">Kreditrechner</a>
