The majority of regular Twitter users are probably familiar with the hashtag, characterized by the symbol # followed by a word indicating some concept or event. For instance, #followfriday is one you’ll see fairly regularly on Friday’s. It’s used to recommend people to follow and it’s become a Friday ritual. For example:

The purpose of the hashtag is to add some structure to the huge amount of messages flowing through Twitter every minute. By adding a hashtag, it makes Tweets easier to search for and aggregrate by topic. Some of the stuff I’ve written about this week was announced at the Where 2.0 conference in San Jose, California and much of it I first heard about by searching for #where20 on Twitter. But while hashtags are a great way to add some structure to one of the most unstructured data sets on the web, it’s not a perfect solution.
Yesterday, popular social media blogger Stowe Boyd argued that physical location, when mentioned in a Tweet, is not properly compatible with hashtags and he’s right. For one thing, hashtags were originally conceived to indicate conceptual ideas in order to make it easier to follow topical conversations. Indicating your physical location isn’t necessarily intended to provoke conversation. Secondly, as Stowe points out, one word location indicators can often overlap with products, events and ideas. In one of his examples of this he uses the hashtag #WhiteHouse. It’s easy to this use hashtag to indicate location, right? Tweet something like “Just arrived at the #WhiteHouse.” But in reality the majority of the users utilizing this particular hashtag will probably be involved in some type of political conversation. So while you could use #WhiteHouse to indicate location, it’s ultimately not the best way to structure it because it becomes meshed in with a plethora of Tweets discussing politics.
So this is what Stowe proposes: /location. Rather than using a #, an / is used so, in the White House example you might say “Just arrived at the /WhiteHouse.” That would indicate the White House is a place at which you just arrived and wouldn’t fall in to the wrong data set. And as for multiple word locations, Stowe proposes beginning and ending with a /. For example, I could say “I’m at home in /winnipeg, manitoba, canada/.” Or it could look like this:

This makes sense to me. While it’s not a perfect solution, it is a step in the right direction when it comes to structuring Twitter data. And Stowe’s Twitter tools startup, Edglings, is working on an application called Thweres that will make use of the new structure.
I’ve always thought that Twitter could obliterate the mobile LBS industry if it incorporated location natively. I’d love it if I could open Twitter on my mobile phone and automatically have people Twittering near me pop up in a dedicated list. But with that comes costs, whether it be in the form of acquiring GPS fixes or revamping the site architecture. And given that Twitter is still working on business model that’ll carry it to profitability, I don’t think adding location metadata is high up on the list of priorities. However, a third-party Twitter client like Thweres could be a great substitute from an end user perspective and I’m looking forward to trying it out. After all, location is ‘in’.
